DES MOINES, Iowa- It's primary day in Iowa, and voters in the state that kicked off the presidential nominating season now are set to choose general election candidates for state offices.
The top contest on the primary ballot Tuesday is the Democratic race to choose a challenger for longtime Republican Sen. Chuck Grassley.
Patty Judge, a former state lieutenant governor, was recruited by national Democrats to take on Grassley, who has faced scrutiny for rejecting hearings for a U.S. Supreme Court nominee. Judge's main competitor in the four-person race is state Sen. Rob Hogg, a more liberal candidate with key endorsements from labor groups but less fundraising.
Candidates also are seeking primary victories in three of Iowa's four congressional districts and legislative contests.
Polls will be open from 7 a.m. to 9 p.m.
