Republican candidate loses US House primary in victory for pro-Israel lobbyists

John Hostettler of Indiana, whom pro-Israel groups deemed antisemitic', loses to Mark Messmer, who led opponents with 40% of vote

Republican John Hostettler has lost his House primary in Indiana, delivering a victory to pro-Israel groups who sought to block the former congressman from returning to Washington. The groups attacked Hostettler as insufficiently supportive of Israel at a time when criticism of Benjamin Netanyahu's government has hit new highs because of the war in Gaza.

When the Associated Press called the eighth district primary race at 7.49pm ET, less than an hour after the last polls closed in Indiana, Mark Messmer led his opponents with 40% of the vote. Messmer, the Indiana state senate majority leader, will advance to the general election in November, which he is heavily favored to win because of the district's Republican leanings. The victor will replace Republican congressman Larry Bucshon, who announced his retirement earlier this year.
