He's going for the simple right to vote. Remember, if he tells you what he's going to do, believe him. He indicated after the 2024 election that "this would be the last time."

Trump pledges effort to eliminate mail-in voting
The president has for years railed against the system, arguing it led to election fraud in 2020.

There are states that do all of their voting by mail. Texas has made it harder for many people unless they are over 65, disabled, or have a damned good excuse. They used to let people register when they renewed their driver's license, etc. Now even to vote by mail you have to request to vote by mail every year.

Voting by mail is more beneficial for the Democratic party because many of the people who would vote Democratic can't get away from work to go to a polling place.

Right now in Fort Worth they're trying to cut in half the number of polling places, and you guessed it, the ones they're wanting to remove are in brown and black districts.

All of this is the last hurrah for the old white male in America. They can't stand that they're out of power so they're forcibly removing everyone else's ability to vote or legislate at all.
