Mitt Romney has pulled into a tie with Newt Gingrich for the first time since the beginning of November, according to the latest Gallup daily tracking poll.
The two presidential candidates are now tied nationally among registered Republican voters at 25 percent.
Gingrich has also seen his support collapse in Iowa, where according to a Public Policy Poll released Wednesday, he has fallen from first place at 27 percent into the second tier of candidates — just ahead of Rep. Michele Bachmann (R-Minn.) at 13 percent.
Rounding out the field in the Gallup national poll, which is based on a five-day rolling average, are Ron Paul at 11 percent, Rick Perry at 8 percent, Bachmann at 5 percent, Rick Santorum at 4 percent, and Jon Huntsman at 1 percent.
Twenty-five percent is the highest Romney has reached in the Gallup poll. The former Massachusetts governor has climbed 1 percent daily since Dec. 21.
