They overwhelmingly approved a map for congressional districts that could help Democrats win five more seats in the U.S. House. The ballot language itself referred to Texas, where Trump convinced Republican leaders to draw new lines this summer aimed at turning five seats for his party.

So far, the GOP has gained an edge in five seats in Texas, one in Missouri, one in North Carolina and a potential net gain of one to two in Ohio.

That means the GOP could pick up nine or so seats in the midterms next year, with the potential to pick up another four or five if Republicans in Indiana, Kansas, Florida or Louisiana decide to redistrict. But that scenario could change if court challenges prevail, among other factors.
