Caucus day has seen a flurry of stories about potential second-choice deals on the Democratic side.

Officially, the campaigns have denied any moves to back another candidate.

But IowaPolitics.com has learned in eastern and southern Iowa, caucus-goers on the ground supporting Sens. Joe Biden and Chris Dodd may help each other become viable on the second ballot.

And in some regions, New Mexico Gov. Bill Richardson's supporters may be moving toward Sen. Barack Obama if Richardson is not viable.

One Democratic caucus veteran insider said the move to make the lower-tier candidate viable or to cast support to Obama is a strategy to prevent Sen. Hillary Clinton from gaining momentum going into New Hampshire.
