Republican presidential candidate Texas Gov. Rick Perry prior to a debate at Constitution Hall November 22, 2011 in Washington, DC.
Rick Perry is drawing standing-room-only crowds in Iowa even though many aren't planning to support him.
Michele Bachmann is meeting with die-hard fans wanting to hear from her even though she has lost her voice.
And Rick Santorum is pitching his candidacy to undecided caucus-goers even as he asks them for cash to keep his presidential bid afloat.
With all eyes on the Republicans leading the pack -- Mitt Romney, Newt Gingrich and Ron Paul -- this other trio of candidates is hoping that hand-to-hand campaigning pays off. Time is running short for them and they have nothing left to lose with little more than a week before Jan. 3's lead-off caucuses.
Perry, Bachmann and Santorum will soon find out if retail politics proves enough for their struggling bids.
