Iowa voters have elected Republican Charles Grassley to a sixth Senate term, extending a political career that dates to 1958.
The 76-year-old Grassley won Tuesday despite calls from Democratic challenger Roxanne Conlin to replace him with someone who hadn't been in Washington for decades and who would offer new ideas.
Grassley responded that he returns to Iowa most weekends and hadn't forgotten his roots. He also argued that his seniority helps Iowa because it allows him to serve on key Senate committees.
Grassley has taken traditional Republican stands against government spending, and he opposed federal health care reforms. But he's also known for leading inquiries into other matters, including misspending in low-income housing programs.
