While we're waiting for more results, let's check in on the issues Indiana voters are focused on in this election. According to a March Emerson College/The Hill poll, 44 percent of voters who said they planned to vote in the Republican primary named "the economy (jobs, inflation, taxes)" as the most important issue facing the state, far higher than the second most chosen option of immigration, which was selected by 17 percent of GOP primary voters, and crime, selected by 12 percent. No other issue was chosen by more than 7 percent of GOP primary voters.

Democratic primary voters, on the other hand, see things very differently: Just 18 percent chose the economy, while 25 percent selected "threats to democracy." Another 16 percent chose "abortion access" and 10 percent chose education.

Tonight, we'll be monitoring how candidates of color perform in primaries for governor, U.S. Senate and the U.S. House of Representatives. Overall, 11 people of color are running in these contests — six Republicans and five Democrats.

The most likely primary winner is Democratic Rep. André Carson, who is Indiana's lone Black representative on Capitol Hill (and was also only the second Muslim ever elected to Congress). Democrats in the solidly blue 7th District look set to renominate him against two little-known Black Democrats.

In the dark-red 4th District, insurance executive Rimpi Girn is an Indian immigrant who has raised at least a little money, so she may be the favorite for the Democratic nomination — but a November defeat against GOP Rep. Jim Baird is a near-certainty.

In the Democratic primary for U.S. Senate, clinical psychologist Valerie McCray is running a long-shot race to become the state's first Black U.S. senator. She ran for the state's 2022 Senate contest but failed to make the ballot and briefly ran for president in 2020. However, she's raised only $14,800, less than the $112,000 former state Rep. Marc Carmichael has brought in. Still, either Democrat will be a huge underdog against Rep. Jim Banks in the general election.

It's less clear if any candidate of color has a shot at winning a GOP primary. On paper, the contender with the best chance might be "Honest Gabe" Whitley, who has raised $364,000 in the solidly Democratic 7th District, making him the only Republican in that race to have reported raising anything. But Whitley is a lightning rod of controversy: Among other things, he faces accusations of concocting false donors and a fictional veterans organization to back his candidacy.

In the 5th District, speech-language pathologist and business owner Raju Chinthala is running, but he's unlikely to finish ahead of the incumbent Spartz or her leading challenger, Goodrich. Two Republican Latino candidates are running in the 1st District — Mark Levya and Ben Ruiz — but Lake County Councilmember Randy Niemeyer is the party's preferred candidate to take on Democratic Rep. Frank Mrvan.

Lastly, the best-known Republican on this list is Curtis Hill, who is making a long-shot bid for governor. Hill lost renomination for state attorney general in 2020 after allegations came out that he had groped a group of women at a party.

Tonight we'll be tracking how anti-abortion candidates fare in Indiana's Senate, House and gubernatorial races.

Of the state's nine congressional seats, four have crowded Republican primary fields. Multiple Republican candidates in those races fall under our definition of being anti-abortion, as do four of the six Republicans running for for governor and Banks, the sole Republican candidate for Senate.

Indiana's Republican-led legislature passed a near-total abortion ban in 2022, and polls showed such an extreme ban was unpopular; Indiana voters are broadly supportive of abortion rights. But the state's Republicans didn't pay an electoral price for enacting the ban in the November 2022 elections, so we'll see how these candidates fare tonight and in November.

We're starting to see the first results trickle in in Indiana, but you just have to look at another Indiana election to see why you shouldn't overreact when only 1 percent of the vote is reporting ...
