Newt Gingrich is rising like a rocket. He’s the new Republican presidential front-runner. He’s en fuego, if you know what we mean.

The latest evidence of this is a just-out Iowa Poll, which puts Mr. Gingrich in the lead in the Hawkeye State as the choice of 25 percent of likely caucusgoers. Rep. Ron Paul of Texas is second, with 18 percent, and former Massachusetts Gov. Mitt Romney is third, at 15 percent.

If anything, Gingrich does even better in national surveys. Right now he’s getting about 27 percent of the GOP vote, according to RealClearPolitics rolling average. Mr. Romney is second, at 20 percent.
