April McClain Delaney

Trone announced he would challenge McClain Delaney in December, citing in part her vote for the Laken Riley Act, a Republican-led immigration bill. McClain Delaney later said she regretted the vote, saying she hadn’t imagined “the horror” of Trump’s immigration enforcement would come to pass.

Trone almost entirely self-funded his attempt to return to Congress. He previously represented the 6th District for three terms but gave up his seat to run for Senate in 2024, losing in the primary to now-Sen. Angela Alsobrooks (D-Md.). McClain Delaney, who is married to former Rep. John Delaney (D-Md.), won an open primary and was elected to the seat that year.

The seat is considered safe for Democrats for the midterms. McClain Delaney won by a bit more than 6 points in 2024.
