There are two Republican races going on in Iowa ahead of Monday's caucuses, according to a new poll: The race for first place between Donald Trump and Ted Cruz, and the race for fourth place among a gaggle of unpopular candidates. In the middle? Marco Rubio.
The Quinnipiac University poll shows the Florida senator a distant third to Cruz and Trump but further ahead of the rest of the field: Trump is at 31 percent, Cruz at 29 percent and Rubio at 13 percent, with no other GOP contender about 7 percent.
Jeb Bush received 4 percent support, behind Ben Carson (7 percent) and Rand Paul (5 percent). The poll's error margin is 3.8 percentage points.
"One week before the caucuses gather, the question is which candidate has the best field organization," Peter A. Brown, the poll's assistant director, said in a statement. "If the events of the last two weeks haven't moved the needle, one wonders what would change in the next six days."
