After a bad defeat in the Nevada caucuses, the options dwindle for former Speaker Newt Gingrich.

Gingrich has benefited in the past from game-changing debates, but there is no debate on the calendar for two weeks.

Gingrich can continue to fight (and lose), go crawling to Romney for and adviser job or drop out now.

The voting calendar looks equally ugly for Gingrich. Republicans have three contests Tuesday: caucuses in Minnesota and Colorado, and a nonbinding primary in Missouri. Gingrich is not even on the ballot in Missouri, and caucuses favor the better-organized Romney campaign. Maine finishes its caucuses on February 11, meaning, most likely, more bad news for Gingrich.
