GOP primaries

Newt Gingrich is scrambling to regain his footing after several polls released Monday showed him in a freefall.

The Republican presidential candidates came down hard on frontrunner Newt Gingrich for his past marital infidelities.

Former Louisiana Gov. Buddy Roemer won’t be endorsing the Republican presidential nominee if Newt Gingrich wins.

Republican presidential hopeful Rick Santorum told Radio Iowa on Monday that his GOP rival Newt Gingrich is taking too much credit for Republican accomplishments during the former House Speaker’s tenure.

A new poll shows Gingrich ahead of Romney in Iowa and gaining 19 points in New Hampshire since October.

Gingrich has Mitt Romney worried, but to win, he must first clear major hurdles.

"Mitt Romney is the tin woodman without the heart, and Rick Perry is the scarecrow," Frank said on Sunday.

Republican presidential candidate Rick Santorum said Herman Cain made the "right decision" in suspending his campaign.

"Herman's gone through a very difficult time," he said on ABC's "This Week." "I think he made the right decision to leave for his family and the country. It clearly was a distraction that wasn’t going to go away."

Sen. Tom Coburn said Sunday that he could not support GOP presidential candidate Newt Gingrich.

Bachmann said her campaign has been in talks with Herman Cain's suspended campaign about a potential endorsement.
