CASI A PUNTO para el caucus de Iowa:

The Des Moines Register’s latest Iowa Poll shows a surprise three-way match-up in contention to win the Iowa Republican caucuses: Mitt Romney, Ron Paul and Rick Santorum.

Santorum, who has been largely invisible in the polls throughout the campaign season, is now beating the other evangelical choices and has a clear shot at victory Tuesday night.

But political analysts note there’s little time for Santorum to cash in and regroup before New Hampshire, where voters weigh in nine days from now, while Romney is positioned to replicate what he’s done in Iowa in all the early states.

In four days of polling, Romney leads at 24 percent, Paul has 22 percent and Rick Santorum, 15 percent.

But if the final two days of polling stand alone, the order reshuffles: Santorum elbows out Paul for second.
