Indiana steps into the national spotlight Tuesday with a primary election that could play a significant role in deciding Republican and Democratic presidential contests, as well as a spirited Senate GOP primary election and crowded races for Republican nominations in two U.S. House districts. Two state Senate Republican primaries also are drawing attention as Senate leaders try to fend off challenges.
Voters cast a record number of early ballots and high turnout was reported Tuesday, especially in some heavily Republican counties in suburban Indianapolis.
Candidates from both parties have traversed the state over the past two weeks, visiting local hotspots and flooding the airwaves with ads.
Indiana has 57 Republican and 92 Democratic delegates for their party national conventions this summer.
Thirty of the Republican delegates will go to the winner of the statewide primary vote. GOP rivals Donald Trump or Ted Cruz are likely to share the remaining 27 delegates as three are awarded to the winner in each of Indiana's nine congressional districts. Trump is looking to strengthen his front-runner status. Ohio Gov. John Kasich effectively ended his Indiana campaign last week with a deal letting Cruz face Trump head on.
Indiana's Democratic delegates are awarded based on the vote percentage for Hillary Clinton or Bernie Sanders in each congressional district.
CONGRESS AND SENATE
Republican U.S. Reps. Marlin Stutzman and Todd Young are vying for the U.S. Senate seat now held by retiring GOP Sen. Dan Coats. They've had a contentious campaign during which Stutzman has characterized Young as an establishment pawn. Young has attacked the tea party-backed Stutzman as an ideologue who prioritizes obstructionism over passing legislation.
The winner will face former U.S. Rep. Baron Hill, who is unopposed for the Democratic nomination.
The Stutzman-Young Senate race prompted big fields of candidates for the congressional seats they are leaving.
In southern Indiana's 9th District, the packed GOP contest includes state Attorney General Greg Zoeller as well as state Sens. Erin Houchin of Salem and Brent Waltz of Greenwood. First-time candidate Trey Hollingsworth has been accused of trying to buy the seat with more than $1.7 million from himself and his father after moving to Jeffersonville in September from his native Tennessee.
State Sen. Jim Banks of Columbia City faces agricultural businessman Kip Tom of Leesburg and fellow state Sen. Liz Brown of Fort Wayne for the 3rd District in northeastern Indiana.
LEGISLATIVE LEADERSHIP CHALLENGES
Two top leaders of the Indiana Senate face Republican primary challengers attacking them over legislative moves in recent years after breezing through previous election cycles.
Senate President Pro Tem David Long of Fort Wayne faces criticism from social conservatives for pushing an unsuccessful proposal this year that would have extended state anti-discrimination protections to lesbian, gay and bisexual people. He faces John Kessler, director for Indiana University-Purdue University Fort Wayne's Center for Economic Education.
Scott Willis, a Westfield business owner challenging Senate Appropriations Chairman Luke Kenley of Noblesville, argues Kenley hasn't done enough to boost funding for schools and road projects in the fast-growing suburban area north of Indianapolis.
LONG LINES FOR SOME
Some Indiana voters encountered long lines at polling sites as they ventured out on a rainy Tuesday to cast ballots in the state's closely watched primary election.
Voter turnout was heavy in Johnson County, just south of Indianapolis, where clerk of the courts Sue Anne Misiniec said more than 6,400 people voted in the first 2 ½ hours after polling sites opened Tuesday. She said the county could see a 50 percent voter turnout.
But Allen County in northeastern Indiana had seen only about a 13 percent voter turnout by midmorning, much of it in Fort Wayne, Indiana's second-largest city.
County election director Beth Dlug (Duh-lug) said about 20,000 people had voted Tuesday by about 9:30 a.m. EDT. Another 16,000 voted ahead of the primary.
Early voter turnout has hit record highs in Indiana.
Indiana Election Division Co-Director Angie Nussmeyer said 286,219 completed ballots had been received by county officials by 8 a.m. Tuesday. That's about 97.6 percent of the more than 293,000 ballot applications requested statewide.
The previous record for an Indiana primary was about 185,700 absentee ballots cast for 2008's primary that featured the tight race between Barack Obama and Clinton for the Democratic presidential nomination.
About 63 percent of the absentee voting applications were for Republican ballots.
Nussmeyer said she doesn't know if the jump in early voting will mean higher overall primary voter turnout.
WHAT VOTERS SAY
Some Indiana residents who voted in Tuesday's primary say they had strong reasons for voting in the state's presidential contests.
Ben Swisher of Indianapolis said he voted for Bernie Sanders in the Democratic primary because the Vermont senator hasn't taken much money from big corporations.
The 41-year-old warehouse manager says a lot of the decisions made by the government "have been based on what would benefit a large corporation and not the American people in general."
David Rogers, a 61-year-old Indianapolis minister, says he voted for Hillary Clinton in the state's Democratic primary largely because he dislikes Donald Trump, the Republican front-runner who may be facing the former secretary of state in November's election.
Rogers says he doesn't like the way the Trump has degraded people in his campaign.
VOTING ON TUESDAY
Polling locations around the state are open 6 a.m. to 6 p.m. local time, so the 12 of Indiana's 92 counties that are in the Central time zone close an hour after those in the Eastern time zone.
Voters can confirm their registration, find their polling sites and get information about candidates on their ballots online .
