Another primary challenge to a sitting Republican representative has fallen short. ABC News reports that Bacon is projected to win the Republican primary in Nebraska’s 2nd District. With 37 percent of the expected vote in, he is defeating Frei, his right-wing challenger, 70 percent to 30 percent.

ABC News is reporting that Miller is projected to win the GOP primary against her challenger, Evans. She has 64 percent of the vote with a little more than a third of the expected vote reporting.

Miller has stood by Trump and even voted to overturn the 2020 election results, but that didn't stop Evans from calling her a "commie RINO." The primary was more evidence that state Republican Parties have been tearing themselves apart over issues like loyalty to Trump and the 2020 election results, even as there are only small differences between candidates.

ABC News reports that Riley Moore, the state treasurer, will win the GOP nomination in West Virginia's 2nd District. He'll be a shoo-in for the general election this fall and will take his seat alongside his aunt, Shelley Moore Capito, who is set to be the state's senior senator at the beginning of next Congress.

This Olszewski ad might be my favorite of the cycle so far. He’s shamelessly capitalizing off the success of the American League East-leading Baltimore Orioles — nicknamed the O’s — one of the most exciting young teams in baseball.

Welcome to 538’s live blog of the May 14 primaries in Maryland, Nebraska and West Virginia! But this is no ordinary live blog. Today, my friends, is arguably the most interesting downballot primary day of the cycle.

The headliner today is the Democratic primary for Maryland’s open Senate seat. The Old Line State could become only the third state to elect a Black female senator, but a wealthy white congressman has spent nearly $62 million (!) to make sure that doesn’t happen. Some have argued that this should-be-safely-Democratic seat could be competitive in the fall if Democrats nominate the wrong candidate, but is that really true? We’ll discuss.

Elsewhere, Republicans could cripple their chances of winning Nebraska’s swingy 2nd District in November if they nominate a far-right primary challenger over a moderate incumbent. Meanwhile, we have one race tonight where someone who spent three months in jail for storming the Capitol on Jan. 6 could return there as a U.S. representative, and another that includes a former Capitol Police officer who was there that day.

And that’s just scratching the surface; we’ll be going deep on primary races up and down the ballot. The polls close in West Virginia at 7:30 p.m. Eastern, in Maryland at 8 p.m. Eastern and in Nebraska at 9 p.m. Eastern. Plan your evening accordingly!
