DES MOINES, Iowa (AP) -- Rick Santorum and Mitt Romney are in a seesaw battle in Iowa's Republican presidential caucuses.
Texas Rep. Ron Paul has been running a close third.
Returns from nearly 90 percent of the state's 1,774 precincts showed Santorum, a former Pennsylvania senator, and Romney, former governor of Massachusetts, closely separated.
It's a fitting conclusion to a race as jumbled as any since Iowa gained the lead-off position in presidential campaigns four decades ago.
The winner could claim bragging rights -- and perhaps much more -- as the Republican nominating campaign makes the turn to primaries in New Hampshire on Jan. 10, then South Carolina and Florida before the end of January.
