2012 Republican Presidential Candidate, Rick Santorum | featured news

Rick Santorum defended his late-night e-mail endorsing former GOP presidential rival Mitt Romney... But the timing -- and the fact that Santorum didn't get around to saying he was backing Romney until the 13th paragraph of the letter -- sent a message that Santorum's endorsement was tepid. He dismissed that idea.

Rick Santorum is endorsing his one-time bitter rival Mitt Romney in a late-night e-mail to his supporters. Santorum on Monday urged his supporters to join him in working with the effective Republican nominee to deny President Barack Obama a second term.

Rick Santorum and Marco Rubio are the top two choices among Republican voters as Mitt Romney's vice presidential running mate, according to a Reuters/Ipsos poll released on Thursday.

Bowing to the inevitable, Rick Santorum quit the presidential campaign Tuesday, clearing the way for Mitt Romney to claim the Republican nomination. Santorum, appearing with his wife and family in his home state of Pennsylvania, told supporters the race for him was over, but the fight to defeat President Barack Obama would go on.

Although Rick Santorum won North Dakota's Republican presidential caucuses on March 6, the Associated Press reports that at last weekend's state party convention Mitt Romney ended up with the most supporters among the state's 28 delegates to the Republican National Convention.

Republican presidential candidate Rick Santorum, in what may be a grim development for his campaign, has lost the lead in his home state of Pennsylvania to front-runner Mitt Romney, according to a poll released on Thursday.

The Rick Santorum campaign is formally calling on Newt Gingrich to drop out of the race and endorse the former Pennsylvania senator, following Tuesday night's three-primary sweep by Mitt Romney. Santorum's communications director Hogan Gidley made the statement during a Wednesday appearance on MSNBC.

Polls are open in Maryland, the District and Wisconsin, where Tuesday’s Republican primaries could move Mitt Romney closer to a nomination that has hovered just out of his reach. Romney is favored to win in all three jurisdictions: the closest race appears to be in Wisconsin, where recent polls have shown him with a single-digit lead over former Sen. Rick Santorum (Pa.)

The former Pa. senator leads among likely GOP voters back home, but nearly 4 in 10 could change their minds before the April 24 primary.

A Rick Santorum TV ad morphs an image of Obama into Romney, making the point that there are no policy differences between the two.
