Former Massachusetts Gov. Mitt Romney continues to lose support nationally, according to the new Gallup tracking poll of the Republican race out Monday. Romney clings to just a one point lead on former House Speaker Newt Gingrich, 29 – 28.

To put it in perspective, Romney was up on Gingrich by ten on Friday. Less than a week before that, he was up 23 points after he had won the Iowa caucuses (which was later confirmed to be won by former Pennsylvania Sen. Rick Santorum) and the New Hampshire primary, which Romney dominated. But his loss in the South Carolina primary has clearly caused many Republicans nationally to reconsider Gingrich.
