Tom Latham's surprise announcement last month that he would retire from the U.S. House at this end of this term was also an unusual exit in modern Hawkeye State history. Over the last 50+ years since the 1962 cycle, only six of 32 Iowa U.S. Representatives - including Latham - left the chamber via retirement, or 18 percent: Democrats Merwin Coad in 1962 and Berkley Bedell in 1986 and Republicans Charles Hoeven in 1964, Harold Gross in 1974, Cooper Evans in 1986, and Latham in 2014. Seventeen others were defeated in reelection bids, while nine ran for higher office. Five of these were defeated (Republicans Tom Tauke in 1990, Fred Grandy in 1994, Jim Lightfoot in 1996, Greg Ganske in 2002, Jim Nussle in 2006), three were victorious (John Culver in 1974, Chuck Grassley in 1980, Tom Harkin in 1984), with one yet to be determined (1st CD Democrat Bruce Braley, running for U.S. Senate this cycle).
