DES MOINES, Iowa (AP) — The race for Iowa's open Senate seat could be dubbed the Resume vs. the Personality. In a contest that could determine which party controls the Senate next year, Democrat Bruce Braley is focusing mostly on his policy positions, and his recent television ads have featured others talking about the four-term congressman's record. In the primary campaign, competing for Republican voters, "she came across as really tough," said Dianne Bystrom, director of the Center for Women in Politics at Iowa State University. Braley, 56, a former courtroom lawyer from Waterloo, emphasizes his work in Congress or criticizes Ernst for her conservative positions, questioning her support for programs like Social Security and Medicare. At a recent event with senior citizens, Ernst repeatedly told attendees she wanted to look for "solutions" to maintain the Social Security program.
