Gingrich leading in Iowa

Newt Gingrich has surged to the lead in Iowa, according to a survey released by the Des Moines Register on Saturday.

The former House speaker has the support of 25 percent of likely Republican caucusgoers in the survey, up from just 7 percent in the previous one conducted in late October.

Rep. Ron Paul of Texas placed second with 18 percent, followed by former Massachusetts Gov. Mitt Romney at 16 percent.

Some of the candidates working hardest for a strong showing in the leadoff caucus state are in the back of the pack. Rep. Michele Bachmann of Minnesota has 8 percent support, equaling Herman Cain, who announced Saturday he was suspending his campaign. Former Pennsylvania Sen. Rick Santorum and Texas Gov. Rick Perry were tied at 6 percent.
