Mike Huckabee is the current Iowa GOP frontrunner, according to April 19 Public Policy Polling results.

Host of the Fox News show "Huckabee," the Republican earned 27 percent of usual caucusgoers’ support. Former Massachusetts Gov. Mitt Romney earned 16 percent, and businessman Donald Trump earned 14 percent.

The report said that if Huckabee doesn’t run, Romney will be the nominal frontrunner. Trump, however, did not garner much interest from Iowans.
