DES MOINES, Iowa (AP) -- They are barely blips in presidential
polls and their campaign cash is scarce.
Some are running on empty, fueled mainly by the exposure that comes with the blizzard of televised debates and interviews they eagerly grant to skeptical reporters.
Yet the second-tier candidates for the Republican presidential
nomination soldier on.
They argue that the race is far from over and that anything can happen with polls showing a wide-open race in Iowa five weeks before the Jan. 3 caucuses.
More than energy and determination, also-ran candidates like
Rick Santorum and Michele Bachmann rely on particular issues, free
media and prospects for the future to drive them to keep their
small-scale operations going.
Santorum, Bachmann and others are likely to remain in the race
until voters have their say.
