ABC News reports that Kim Klacik is the Republican's nominee for Maryland's 2nd. Klacik also ran in 2020, when her ad that followed her walking the streets of Baltimore in a red dress and heels went viral. You could write a book about how Republican women campaign for Congress (and people have, FWIW). Klacik's would earn its own chapter, if I was writing it!

That was quick. Just minutes after Hogan was projected the victor in the Republican primary, the Democratic Senatorial Campaign Committee is out with a new digital ad, using his own words against him — spotlighting Hogan calling himself a "lifelong Republican" (a not-so-veiled attempt to paint him as anything but moderate).

Democrats know the balance of the Senate is at stake here. They seem to be wasting no time reminding everyone else.

It's 8 p.m. Central, and the polls are now closed in the final state we're watching tonight: Nebraska.

He may be new on the national scene, but us Marylanders have been watching Johnny O's career with great interest for nearly two decades. He got to the state house in 2006 at just 24 years old and has been pegged as a rising star ever since then. At just 41, he's young enough to be a credible Senate or gubernatorial candidate down the line.

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!
