Former President Donald Trump continued his drive to punish even partial opposition inside the GOP in Tuesday’s primaries, while the party also flipped a longtime Democratic House seat in a South Texas special election.

Rep. Tom Rice, one of the 10 House Republicans who voted to impeach the former president, lost his primary to Trump-endorsed state Rep. Russell Fry. It’s the first time this year that a Republican impeachment backer has faced a challenger backed by Trump — and the results were emphatic, with Rice’s party support crashing to just a quarter of the vote.
