CLINTON RIVALS turn to Iowa, where New York senator isn't runaway leader for Democratic nomination.

"Iowa is the closest thing we're going to get to a fair fight -- and it's a six-man cage match," says Biden aide Larry Rasky. Biden trails badly, but Rasky says he is heartened by big crowds for Clinton and Obama because they prevent the personal interactions Iowans demand.

Also encouraging to dark horses: Obama's $3 million in Iowa TV ads last month didn't boost his poll numbers, and his numbers in New Hampshire flag.

Obama camp hints Illinois senator is girding for fight with Clinton to make up ground.
