The Newt Gingrich surge has moved him to the top of the polls in Iowa, big gains in New Hampshire and now a two-point edge over President Obama in a hypothetical general election match-up.

A new Rasmussen Reports national telephone survey of Likely Voters finds Gingrich attracting 45% of the vote while President Obama earns support from 43%. Six percent (6%) prefer some other candidate, and six percent (6%) are undecided.

Last week, Gingrich trailed the president by six. Two weeks ago, he was down by twelve. Earlier in the year, both Rick Perry and Herman Cain followed a similar path to take a slight lead over the president. However, in both cases, their time as frontrunners quickly came to an end. Neither man led the president more than a single time in a Rasmussen Reports poll. It remains to be seen whether Gingrich follows that path or is able to retain his status as the leading alternative to former Massachusetts Governor Mitt Romney.
