The Race
Democrat Jamie Raskin is running for re-election in Maryland's 8th House District, facing Republican Cheryl Riley in the November 3, 2026 general election. The primary contests already happened on June 23, 2026, and they told a pretty clear story about where this race is headed.
Raskin didn't just win the Democratic primary; he demolished it. The incumbent Democrat secured 92.6% of the vote, capturing 83,637 votes out of 81,588 total cast. His challengers barely registered: J. D. Kumar, Boris Velasquez, and Stephen Leon each pulled in around 2,000-2,200 votes. Riley, meanwhile, claimed the Republican primary with 6,101 total votes cast, a number that tells you everything about the district's partisan lean.
Ratings
All three major rating outfits agree: this is a slam dunk. Cook Political Report, Sabato's Crystal Ball, and Inside Elections all rate Maryland's 8th as "Solid Democratic." That's not "lean Democratic" or "likely Democratic," it's "solid." The consensus rating as of mid-June was crystal clear: this seat belongs to Democrats.
Prediction Markets
Bettors on Kalshi and Polymarket aren't hedging their bets. As of June 29, 2026, the prediction markets gave Democrats a 96.9% probability of holding the seat, with Republicans at just 3.1%. That's not a forecast; that's a coronation.
Experts vs. Markets
Here's what's wild: the expert raters and the prediction markets are essentially saying the same thing. Both see a dominant Democratic seat with virtually no pathway for a Republican upset. No daylight between the polls and the bettors. The district voted overwhelmingly for Raskin in the primary, the experts rated it safely blue, and the money followed suit. Four candidates will appear on the November ballot, but everyone, from political analysts to high-stakes gamblers, knows how this one ends.
