A new Iowa NBC News/Marist poll shows that voters in that state have not settled on their choice for Republican presidential candidate and the race remains extremely volatile.
Five candidates received double digit support and a 16% of likely voters are still undecided about which Republican they will support.
The state race has changed significantly since Minnesota Rep. Michele Bachmann won the Ames Iowa straw poll in August. She is tied for fourth with Rick Perry at 10% of the vote.
Only 41% of likely voters showed strong support of the candidate that they picked with, showing that the race can turn quickly when a candidate gains momentum.
