Rep. Bruce Braley (D) leads state Sen. Joni Ernst (R) 44 percent to 40 percent in a new Quinnipiac poll of voters in the race for U.S. Senate in Iowa, in which men have lined up behind the female candidate and women are supporting the male contender.
Women support Braley 47 percent to 36 percent. Men back Ernst by a narrower 44 percent to 40 percent margin.
Both candidates easily won their respective party nominations. The race has tightened since March. When Quinnipiac polled the head-to-head matchup then, Braley led Ernst 42 percent to 29 percent.
The poll was conducted Thursday though Monday.
