The largest single day of voting in the Republican presidential race is two days away, with 419 delegates at stake in 10 states.
Mitt Romney enters with 203 of the 1,144 he needs to secure the nomination. He's coming off his fourth consecutive win, after taking Washington state's caucuses yesterday by a double-digit margin. Today he picked up the endorsement of the No. 2 Republican in the House, Eric Cantor.
Rick Santorum is second in the delegate count with 92, but he's suggesting he could do better if the field narrows. Appearing on "Fox News Sunday," Santorum says he's been splitting conservatives --he describes them as the "anti-Romney vote" -- with Newt Gingrich.
Meanwhile, Gingrich says he has no doubts that the Republican candidates eventually will unite behind the party's nominee, despite the tough rhetoric they've been exchanging during the campaign. Appearing on NBC's "Meet the Press," Gingrich says the GOP's goal is to deny President Barack Obama a second term.
Ron Paul is also seeking to keep his candidacy afloat. He's off to campaign in Alaska, one of the 10 states voting on Super Tuesday.
