More federalism.
If anything changes in Texas politics in 2018, it’ll likely be the work of voters — not mapmakers.
The U.S. Supreme Court’s decision to stick with the state’s current political maps will preserve, for now, the Republican advantages that are baked into these particular biscuits. Specifically, that’s a 25-11 Republican-Democratic split in the congressional delegation, a 20-11 split in the Texas Senate and a 95-55 split in the Texas House. And it appears to squelch efforts by minority and Democratic groups to try to win in the courts some of the districts they've been unable to win at the polls. But the courts still have time to mess with the state’s 2018 elections.
The primaries are set for March 6. Judges say they don’t like disrupting elections, but they’ve done it before and nothing’s preventing them from doing it again.
