ABC News reports that state Sen. Mark Messmer is projected to win the crowded GOP primary in Indiana's 8th District, which is currently held by Rep. Larry Buschon. Messmer defeated former Rep. John Hostettler and several other candidates in a race that attracted significant outside spending.

Indianapolis’s Marion County is reporting votes now in Indiana’s 6th, too. And according to the AP, Shreve is beating Speedy there 38 percent to 29 percent, likely cutting off any chance for the more conservative Speedy to prevail.

The Associated Press has projected that state Sen. Mark Messmer has won the GOP nomination in the 8th District. He will likely win the general election this fall. ABC News is not reporting a projection in the race yet, but Messmer has about 43 percent of the vote — 27 percent more than his closest challenger — with 40 percent of the expected vote reporting.

We’re up to about half of the expected vote counted in Indiana‘s 6th District, and Jefferson Shreve is still holding steady in the lead with 29 percent. Jamison Carrier and Mike Speedy are running behind at 21 and 20 percent, respectively.

In the safely Republican 6th District, Rep. Greg Pence — who, like his brother Mike, is conservative but not angry about it — is stepping aside, and it's very much an open question whether he'll be replaced by a moderate or a hardliner.

Former Indianapolis City-County Councilor Jefferson Shreve, the owner of a successful storage company, is the top fundraiser in the GOP primary thanks to a $4.5 million loan to his own campaign — more than his six opponents have raised combined. But wealthy state Rep. Mike Speedy has also loaned himself $1.3 million and he's using it to remind voters of the moderate positions, like supporting gun control, that Shreve took last year during his failed bid for mayor of Indianapolis (a significantly bluer constituency than the 6th District). To underscore the ideological fault lines of the primary: Shreve has the endorsement of the U.S. Chamber of Commerce, while Speedy is backed by the tea party group Americans for Prosperity and Susan B. Anthony Pro-Life America.

No other active candidate in the race has raised more than $200,000 except businessman Jamison Carrier, who raised the most from actual donors ($115,000) in addition to a $750,000 self-loan. There's a chance that Carrier sneaks up the middle between the two front-runners, as he's the only one of the three from a part of the district that's not Indianapolis, which accounted for just 23 percent of the Trump vote in the district in 2020, according to Daily Kos Elections. There's no polling here, though, so it's hard to know whether Carrier's geographic advantage will erase Shreve's and Speedy's financial edge.
