Trone ended up spending just about $62 million out of his own pocket in Maryland's Democratic primary for Senate, but it wasn't enough for him to defeat Alsobrooks. It also left Trone just short of the all-time record for self-funding in a Senate race. In 2018, now-Sen. Rick Scott spent more than $63 million of his personal wealth on his successful campaign. (He's up for reelection this year.) But to put that in perspective, Scott spent that amount over the course of the whole cycle, whereas Trone shelled out nearly the same total for just the primary!

My main final thought for the night is that we've seen once again how powerful incumbency can be. Incumbents won against far-right challengers in primaries throughout the states. In the race I was watching, West Virginia's 1st, there was very little daylight between the two Republican candidates, Miller and Evans. Both were extremely loyal to Trump and the MAGA agenda, but Evans's candidacy largely hinged on him being more loyal to Trump than his opponent because he actually protested on Jan. 6, while Miller had avoided angering the base by voting against certifying the election. As we race toward an election that appears to be a 2020 rematch, the same 2020 spirit pervades many downballot races as well.

All the races we were tracking tonight have now been projected! What are everyone’s takeaways from the night’s results?

West Virginia actually has a history of casting protest votes against incumbent Democratic presidents in primaries, Irena. For instance, in 2012, Barack Obama beat total rando Keith Judd here just 59 percent to 41 percent. This year, Biden is winning a decent 71 percent of the vote, but he's especially weak in coal country in the southwestern part of the state — for example, winning just 49 percent in Mingo County. But these are no anti-Israel protest votes; coal country is a deeply conservative part of the country that nonetheless still has a lot of registered Democrats. These protest votes, therefore, are protesting the liberal direction that the national party has taken this century.

It's going to be a minute before we start to get primary results this evening, so allow me to make a humble suggestion in the meantime: Listen to the 538 Politics podcast!

Yesterday I sat down with my colleagues Nathaniel and Geoffrey and friend of the pod Leah Askarinam to talk about the recent The New York Times/Siena College swing-state polls and preview tonight's races. In case you missed it, the polling was pretty bad for President Joe Biden. He trailed former President Donald Trump in every battleground state except Wisconsin and lagged by 12 percentage points in Nevada.

But there are some caveats in understanding what those polls mean at this point in the cycle. Most importantly, it's less that Trump has picked up ground than that Biden has lost it, and a big question over the next five and a half months will be whether Biden can gain that support back. There's a lot more to say, but I'll let you listen to find out!

As far as tonight's races go, we mainly focused on the important Democratic Senate primary in Maryland, where things are looking truly competitive. We also hit on a couple of House primaries that feature people who were in the Capitol on Jan. 6, 2021 — one Capitol police officer and one Trump supporter. Check it out!
