Sen. Marco Rubio, R-Fla., may not want to talk about becoming the GOP vice presidential nominee, but he is certainly campaigning like one -- tagging along with Mitt Romney on the campaign trail and taunting President Obama.

He said Monday that if Obama focuses on his current record as president, "he is going to lose and he knows that."

"They don't want it to be about his record. They're going to want it to be about everything else," Rubio said on Fox News' "Hannity" Monday night. 

Asked about becoming a possible vice presidential candidate, Rubio clammed up saying he did not want to talk about it because he was trying "to be respectful of their process."

Earlier Monday, Rubio campaigned for Romney in Aston, Pa., by taking questions from the press at a town hall meeting. Romney said he was "delighted" to be joined with Rubio on the campaign trail. In return, Rubio said Romney is going to help America "reclaim and recapture the things that make this nation of ours different from all other countries on the earth."

During the town hall meeting, Rubio also continued to criticize Obama arguing that he is trying to tell "Americans that the reason why they're hurting is that other people are doing too well. That the way they can climb the ladder is to pull other people down. If we do that, we become like every other country in the world." (read more)

Social media is not just for America's youth, but also America's women -- and sites like Twitter and Facebook may be a factor in winning their votes this year considering women make up about 58 percent of social media users.

"At the end of the day the demographic that's most important is women," James Andrews, a social media commentator and blogger for FastCompany.com, said. "Women dominate the use of social media."

The number of people using networks like Facebook and Twitter doubled between the last presidential election in 2008 and the midterm elections in 2010 to 850 million users.

In that time, though, the proportion of male social media users fell 3 percent, according to the Pew Research Center.

President Obama won 56 percent of the female vote in 2008, helping give him the edge he needed to win the election over Republican rival Sen. John McCain.

Also according to Pew Research Center , 22 percent of online American adults used social network sites or Twitter for politics in the 2010 campaign.

Currently, Obama is leading in the polls among women voters. He is also beating his GOP rivals by millions of Twitter followers and Facebook 'likes.' (read more)

Sarah Palin continues to push for Rep. Allen West as a 2012 vice presidential candidate, calling him a "rogue" choice for the GOP.

"When I talk about going rogue, what I want to do is encourage the GOP nominee to not think that they have to go with somebody necessarily safe," Palin said on Fox News' "Hannity" Tuesday night following the Wisconsin, Maryland and District of Columbia primaries.

"I love that (West) has that military experience. He is a public servant willing to serve for the right reasons. He understands the Constitution. He understands our national foreign policy issues that must be addressed," Palin added.

Palin earlier pitched West, R-Fla., as a possible VP candidate in March. 

The topic of picking a GOP vice presidential candidate was also mentioned when Palin co-hosted the "Today" show Tuesday morning, but she did not mention West's name. 

"What I would advise the nominee, Mitt Romney, or whomever the nominee is: Don't necessarily play it safe and do just what the GOP establishment expects them to do," Palin said. "It doesn't matter if that person has national level experience or not, they're gonna get clobbered by the lamestream media who does not like the conservative message."  (read more)

Mitt Romney left his GOP rivals behind to focus solely on criticizing President Obama's economic policies while campaigning in Wisconsin the night before the state's primary -- as Rep. Paul Ryan voiced confidence that Romney will secure the GOP nomination against Rick Santorum.

During separate interviews for "On the Record with Greta Van Susteren" Monday night, Romney and Ryan both emphasized the need to turn around America's economy and the critical role the issue will play during the general election.

"The president has failed when it comes to caring for the American people," said Romney. "This president's policies have failed. His economic policy has been a bust."

Romney did not speak a word about his GOP rivals during the interview. Ryan, though, said Santorum is not capable of attaining the delegates he needs to win the nomination -- he said Santorum would need about 82 percent of remaining delegates if Romney sweeps the three contests held Tuesday.

"I don't see how he can put it together," Ryan said about Santorum. 

Ryan also said he thinks Romney has the best chance of beating Obama in the general election. (read more)

Rick Santorum, looking for encouragement as Mitt Romney steps ever-closer to the Republican nomination, is casting his campaign as a Final Four surprise.

He compared the race to the Kansas-Ohio State semifinal basketball game Saturday night in which the Kansas Jayhawks surged from behind to beat The Ohio State Buckeyes by 2 points in the NCAA Final Four.

"We aren't even at halftime folks," Santorum told a crowd of supporters while campaigning in Mishicot, Wis., before Tuesday's primary. "Not even half the delegates have been selected in this race."

The Kansas basketball team will go on to play in the NCAA championship game Monday night against Kentucky while Santorum continues to fight against his rival Romney for the GOP nomination. On Sunday, Santorum questioned why Romney is still campaigning in Wisconsin if the nomination is already locked up.

"Why is he spending $4 million in Wisconsin if the race is over?" said Santorum. "It's like telling Kansas last night you're down by 18 points but before halftime. Give up, it's over." (read more)

Mitt Romney, under fire from Rick Santorum for allegedly crafting the precursor to ObamaCare in Massachusetts, explained Tuesday how his approach to overhauling health care at the federal level would be different than the president's. 

Romney, who adamantly opposes the federal health care law, said on "The Tonight Show" that he would want those who have been continuously insured to be able to get insurance going forward.

But he added the security would not be extended to people who apply for insurance once they fall ill.

"If they are 45 years old and they show up and say 'I want insurance because I have heart disease,' it's like, hey guys -- we can't play the game like that," Romney said.

Romney spoke as the Supreme Court prepared to head into the third and final day of debate on the Obama health care law.

Santorum has used the Supreme Court hearing as an opportunity to attack "RomneyCare," saying it is the "blueprint" on which ObamaCare is based. He says Romney can't fight Obama on the issue in the general election.

Solicitor General Donald Verrilli, the federal government's attorney in the case, also told the justices that Congress saw how health care worked "in the state of Massachusetts" and that "it had every reason to think it could work on a national basis." (read more)

Republican presidential candidates Mitt Romney and Newt Gingrich pounced on President Obama's hot mic comment to Russian President Dmitry Medvedev at the 2012 Seoul Nuclear Security Summit -- after Obama mentioned he wanted to wait until after the election in November to discuss the proposal to build a missile defense system in Europe.

"This is my last election," Obama told Medvedev when he thought his microphone was turned off. "After my election, I have more flexibility."

Medvedev replied saying "I understand. I will transmit this information to Vladimir," referring to incoming President Vladimir Putin.

While speaking at a rally in San Diego, California on Monday, Mitt Romney mentioned Obama's conversation with Medvedev labeling the exchange as a "troubling development."

"This is no time for our president to be pulling punches with the American people and not telling us what he is intending to do with regards to our missile defense system, with regards to our military might, with regards to our commitment to Israel, and with regards our absolute conviction that Iran must have a nuclear weapon," he added.  (read more)

If you could have a Secret Service nickname what would it be?

Republican presidential candidate and Texas Rep. Ron Paul, who opted out of Secret Service protection because he thought it was a "form of welfare," jokingly said on "The Tonight Show with Jay Leno"  Tuesday he would like to be called "Bulldog."

"I would go after the Federal Reserve and all that big spending," Paul said. "I'm an ordinary citizen and I think I should pay for my own protection."

There were plenty of laughable moments during Paul's interview. Leno compared a picture of Paul in his bathing suit to a recent and unflattering photo of Sen. Rick Santorum lounging around the pool in Puerto Rico without a shirt.

Leno also played a video with Paul's head superimposed onto a karate fighter, but these antics did not distract Leno from questioning Paul about issues like birth control and how he felt about other presidential candidate's policies.

Paul admitted he did prescribe birth control and the morning-after pill while practicing as an ob-gyn in Texas.

"I was also putting myself out of business, all this birth control," said Paul, adding, "They had less babies." (read more)

Ever since the convergence of politics and social media first gained prominence during the 2008 presidential election, political candidates are expected to engage with their voters in new and creative ways through the Internet. So in the race to gain popularity online who is leading the pack?

On Twitter, Mitt Romney has about 376,000 followers, Newt Gingrich has more than 1.4 million followers, Rick Santorum has close to 165,000 followers and Ron Paul has about 27,500 followers.

They are all dwarfed by President Obama, who dominates the Twitterverse with more than 13 million followers.

Of the GOP candidates on Facebook, Romney last had about 1.5 million likes, Gingrich has 295,979 likes, Santorum has 177,829 likes and Paul with 908,056 likes.

But again, President Obama surpasses all the GOP candidates with 25.5 million likes. (read more)

Mitt Romney thinks Rick Santorum’s latest robo-call in Michigan against him is "outrageous," "disgusting" and a "new low" for the Santorum campaign, but robo-calls have long been and are frequently used as a political tactic in the days before primary elections.

Shaun Dakin, who created stoppoliticalcalls.org -- a nonpartisan and nonprofit website meant to elevate political discourse starting with the creation of the National Political Do Not Contact Registry, said robo-calls are a "study in chaos" and a cheap way for candidates to get their message across.

"They don’t do them because they work," Dakin said. “They do them because they can.”

Dakin said voters receive an uptick in the number of political robo-calls "the very last days of election" and once the election is over they disappear.

"They are really onerous to the consumer," Dakin said. "The bottom line is everyone has a phone."

Santorum is not the only candidate using robo-calls during this year’s primary elections. (read more)
