El día más salvaje de la campaña, y falta el debate

POLITICO.com:

A GOP presidential primary marked by the unpredictable took its sharpest turns yet Thursday and the fallout could determine whether the campaign effectively ends this weekend or continues for weeks or even months.

Over a period of mere hours, the roller-coaster Republican race was shaken by a cascade of events: An explosive ABC interview with Newt Gingrich’s second wife, Marianne, in which she describes his request for an “open marriage”; a recount of the Iowa caucuses revealing that Rick Santorum won more votes than Mitt Romney; and Rick Perry’s abrupt decision to drop out of the race and get behind Gingrich.

And all that took place before the four remaining candidates were to meet on stage here for their final debate before Saturday’s South Carolina primary — an event that could be critical given Thursday’s whirlwind of news.
