Well, you’re right about the fighting part, but wrong on the attempts.
Dozens of states tried to pass election integrity bills after the Trump fiasco. Few got it passed due to Republican intervention.
Same in Congress in both the 117th and 118th. Attempts to make a bipartisan bill always fails because of GOP additions that are absolutely insane.
The opposite has happened in GOP controlled state sessions in places like Texas, Missouri, Wisconsin, Minnesota, and Michigan, where bills have been passed that are very obviously skewed towards the GOP controlling the seats, and getting the benefit of either limiting Democrat control directly, or limiting future abilities of such.
It’s absolutely foul, and though the Democrats are working hard to fight these things, it looks like abject failure before any real attempts can even be made, which voters seem to see as weakness. Maybe that’s just a defeatist point of view though.
