I fully expect an override from the House and Senate before the end of the legislative session in a few weeks, because they’re not going to pass up such a good chance to gerrymander the state’s Congressional map — If some map doesn’t wind up going into law, then the Federal courts will decide the matter, and they’ll probably not create such a favorable map for Republicans.
The override will easily happen in the Senate. As far as the House, they need to peel back a few more Democrats — Several of the big-name St. Louis black Democrat House members have already voted for this map, so you know they’ll be there for the override. I think the horse trading behind that is that Tilley promises to let Nixon’s veto of other Republican-coveted legislation stand without any attempt at an override (e.g. SB 188) in exchange for those few Dems being there to override Nixon’s veto of The Map.
All along, I thought Nixon wouldn’t veto The Map because he knew that an override would happen. Unfortunately for him, black Democrats from St. Louis City, still fuming at him over deseg, would be the ones who would have to sustain his veto.
