Amid the many primaries taking place tonight, voters in Colorado's 4th District are also choosing their next member of Congress. Buck, frustrated with his own party, resigned from the House early, triggering a special election to fill out the remainder of his term.
Though Boebert is running for a full term in this district, she isn't running in the special. Instead, Republicans nominated Greg Lopez, the former mayor of Parker, Colorado, and a 2022 candidate for governor. Lopez faces Democrat Trisha Calvarese, a speechwriter, in what should be an uncompetitive special election tonight.
But there's at least an outside possibility the race could surprise us. Democrats recently overperformed in another House special election, in Ohio's 6th District, that was thought to be a walkover for the GOP. That seat, vacated by Republican Bill Johnson, had voted for Trump by 29 percentage points in 2020, but the GOP nominee won by 9 points, an overperformance of 20 percent. Colorado's 4th District voted for Trump by 19 points in 2020, so a similar overperformance would result in a very tight race.
However, there are plenty of reasons why that may not be the case. Unlike in Ohio, where the special election was the only race happening in the state and turnout was in the basement, the Colorado special election is concurrent with a statewide primary race that will boost turnout. And in the 4th District specifically, a contentious primary featuring Boebert and a bunch of other candidates will probably boost Republican turnout specifically.
But it wouldn't take a Calvarese win to be good news for Democrats. Historically, special election results have some predictive power, and Democrats have been putting together a healthy record so far ahead of the 2024 elections. Since the beginning of 2023, Democrats have overperformed partisanship in House special elections by 7 points, according to a 538 analysis, and in special elections overall by a similar margin.
At a moment when national polling looks middling at best for Democrats, a stronger-than-expected showing tonight could provide some much-needed comfort.
