I dug into this more because I was under the impression it was the case that most states did not: here’s what I found
https://felonvoting.procon.org/state-felon-voting-laws/
23 states let you vote after prison. 9 fully stop you off your rights. DC & 2 State let you vote from prison. The others are some level of parole or parole and probation.
Which means overall 9/51 are full loss: everywhere else you can theoretically get it back.
I heard rumors someone burned his house down. No idea if they’re true or not.
