Bruce Braley talks with local voters Judge Lybbert, right, as Bill Sinnott, back, listens in at Morg's Diner Tuesday, June 3, 2014, in Waterloo, Iowa. The outcome of Tuesday's five-way Senate primary is significant because Iowa, a traditional swing state, is expected to play a key role in the race for U.S. Senate control this fall. Republicans need six seats to gain a majority, and Iowa is seen as a prime opportunity because neither party will have the power of incumbency and because the GOP views Democratic U.S. Rep. Bruce Braley, his party's assured nominee, as vulnerable. (AP Photo/Waterloo Courier, Tiffany Rushing) less
