Bloomberg/DMR Iowa Poll: Senate Candidates Just a Point Apart

Bruce Braley and Joni Ernst are in a dead heat as they both call in surrogates to boost their candidacies.

Republican Joni Ernst, running for the U.S. Senate in Iowa, walks outside the Scott County GOP headquarters during a campaign stop in Davenport, Iowa, U.S., on Thursday, Sept. 25, 2014. In Iowa, where a woman never has been elected to the U.S. Senate or governor, Republicans think their female candidate, Ernst, will enable them to reduce the gender gap.
