Some would, for sure. But some would stick it out. And even in many areas thought of as deeply red, the margin required to flip the result is not that much. If you have a previous voter turnout of 2/3, and just 1/4 of the previous non-voters end up voting because it’s mandatory, that’s an 8 point swing. That would have been enough to swing 4 more states in 2020, as well as Maine’s 2nd district. Or if it were the Democrats responsible for attempted voter suppression, those same stats would see 7 states plus Nevada’s 2nd flip to Republican. That’s looking at the presidential race because the stats were easiest to find and compare, but it’s likely even more pertinent in congressional races. Enough of the races would be close enough to basically guarantee the side supporting people’s democratic rights will win a majority of seats.
