Wisconsin Governor Scott Walker leads another very early Iowa poll.
A Gravis Marketing poll conducted after Mitt Romney announced he would not make a third White House run found Walker in the lead with 24%. Fifteen percent of Iowa Republicans are undecided and, former Florida Governor Jeb Bush and Sen. Rand Paul (R-KY) are tied in second with 10% each.
New Jersey Gov. Chris Christie is next with 9%, followed by Sen. Marco Rubio (R-FL) with 7%; Mike Huckabee with 7%; former Sen. Rick Santorum with 6%; Ben Carson with 5%; Sen. Ted Cruz (R-TX) with 4%; and Carly Fiorinia with 3%.
The poll was conducted February 12-13 and has a four-percent margin of error.
Walker also had the lead in a Des Moines Register poll conducted earlier in the month.
