One is the race in Kansas’ 3rd Congressional District, where Rep. Kevin Yoder (R) is facing a tough race. The National Republican Congressional Committee (NRCC) has canceled more than $1 million in advertising in the coming weeks that had been aimed at bolstering Yoder’s campaign.

Cook also reclassified Michigan’s 11th Congressional District as “lean Democrat” after it was previously considered a “toss-up.” Incumbent Rep. David Trott (R) is not seeking reelection, setting up a race between Haley Stevens (D) and Lena Epstein (R).

The site also shifted two races that previously “leaned Republican” to “toss-up.” One involves Rep. Carlos Curbelo’s (R-Fla.) reelection bid, while the other involves Rep. Mia Love’s (R-Utah) campaign for a third term. Both are considered young, rising stars in the GOP.
