HOUSTON (AP) — Texas Democrat James Talarico launched his general election campaign for the U.S. Senate Wednesday by framing his Republican opponent, state Attorney General Ken Paxton, as part of a corrupt political establishment that uses power to serve itself rather than the people.

Talarico has given Democrats their best chance in years of winning a Senate race in Texas and has boosted their still-uphill chances of retaking the majority in the U.S. Senate in November. Talarico, a former middle school teacher and a state lawmaker from Austin, laid out a clear strategy for the months ahead: Litigating Paxton’s scandals to a weary electorate.
