Three days after a Des Moines Register poll found Ben Carson plowing ahead of GOP frontrunner Donald Trump in the Iowa caucus race, a newly released Monmouth University poll sees the doctor's lead widening further. According to the survey, Carson now leads the pack with 32 percent of the state's Republican vote, followed by Trump with 18 percent, Ted Cruz and Marco Rubio tied at 10 percent, and Jeb Bush at 8 percent. The last Monmouth poll from August showed Carson and Trump tied at 23 percent, and so the retired neurosurgeon has grown nine percentage points while the real estate mogul's support has shrunk by five.
