DES MOINES, Iowa (AP) — Polls have opened as Iowa voters decide a number of key primary election races, including a crowded contest among candidates seeking the Republican nomination to replace longtime Democratic Sen. Tom Harkin.
Five Republicans are vying on Tuesday's ballot for the U.S. Senate seat, which is open due to Harkin's retirement. The winner will face Democratic U.S. Rep. Bruce Braley in the November general election.
Braley's decision not to run for his 1st District seat and Republican Rep. Tom Latham's retirement in the 3rd District also have drawn plenty of candidates for those open positions.
Gov. Terry Branstad, who is seeking a sixth term, is expected to win against his primary election opponent, anti-abortion activist Tom Hoefling. The winner will face Democratic state Sen. Jack Hatch.
Polls close at 9 p.m.
