Staying at Tilt Edwards.
The prospect of an R supermajority in the legislature comes down to 2 rural seats where incumbent independents are in runoffs against R's and 3 inner suburb seats (1 in NOLA and 2 in Baton Rouge) that Trump won by 10ish or less where incumbent R's are in runoffs against D's.
One of the rural seats is almost a certain flip as R's combined for >60% in the 1st round. The other rural seat is being treated as a toss up, but I think it will also flip as Edwards should lose it pretty substantially.
However, the most vulnerable suburban R seat in Baton Rouge only R+4 and includes a college campus. I expect it to flip. If JBE wins, he's probably winning by double digits there. The R incumbent in an R+8 seat in New Orleans is probably a toss up. She is well known for being the most moderate R in the legislature, but of course that kind of reputation didn't help Lance, Curbelo, Comstock, etc. in 2018.
The second rural seat that I assume you are talking about is a independent vs Republican race, ands it's one the independent picked up in a special. It is not a hard R area and has a lot of minorities - it's that area north of BR that is rural not suburban. Edwards I suspect actually carries LA-62 because it's built out of both Feliciana parishes that voted for JBE by over 50% in round 1. The Indie hot all the Dems last time during the runoff, in addition to some R's. So yes, it rightly a tossup and it should stay that way.
