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.

While Romney has remained steadily in the mid-20 percent range throughout December, Gingrich has quickly declined after peaking at 37 percent earlier this month.

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.
