US Republican presidential candidate Newt Gingrich is leading.

Former House Speaker Newt Gingrich, once given up for dead in the Republican presidential primary, picked the right moment for a dramatic comeback. With less than a month to go until voting begins, Gingrich now leads the field of GOP contenders in Iowa, South Carolina and Florida and is within striking distance of the lead in New Hampshire according to a new CNN/TIME/ORC poll released on Wednesday.

In Iowa, Gingrich notches 33% support to Mitt Romney’s 20% among likely caucus goers. Gingrich leads Romney 43% to 20% in South Carolina. And in Florida, Gingrich is leading 48% to Romney’s 25%. These numbers show a meteoric rise: Since the last time this poll was conducted in late October, Gingrich has gained 35 points in South Carolina, 31 points in Florida, plus 23 points in Iowa. Most troubling of all for Romney, Gingrich has posted a 19-point gain in New Hampshire, once a stronghold for the former Massachusetts governor.
