Tried making a nasty R gerrymander.
Seems VRA compliant from what I can tell, though probably lumps a bunch of incumbents together and would be non-viable for that reason.
Insets:
Austin/San Antonio:
Houston:
DFW:
Clinton carried 15 districts, Trump carried 24 in 2016. Pretty sure Trump carried the 15th in 2020 but Biden still carried the 37th.
6th and 3rd might not last the whole decade but given DFW's trends that's unavoidable. The D vote sink in Austin was necessary to prevent the whole area from turning into a dummymander. All districts other than the 6th and 3rd (and maybe the 15th and 37th, with whatever the hell is going on in the RGV) should be safe for the whole decade.
Do you have Beto-Cruz #s?
