REMATCH

Republicans gear up for their second debate of the weekend Sunday night. Five candidates (sans Ron Paul) will sit down for roundtable discussion in New Hampshire.

Forum begins at 8 ET on the Fox News Channel and lasts 90 minutes.

Impact of Saturday's debate continues to reverberate:

Huckabee panned Romney's performance, suggesting he's hypocritical and thin-skinned. Romney unloaded on McCain over immigration and tax cuts. And Giuliani rubbed in Romney's second-place IA finish.
