I see this come up a lot in discussions about voting in America. Postal votes disproportionately go to Democrats, hence the Democrats want to expand postal voting while Republicans want to restrict it (and insist there is totally a bunch of fraud going on).
I’ve googled with a few search engines and haven’t found a convincing reason. Lots of evidence that the skew is real, but no explanation as to why. Indeed, if one just looks at demographics, one would expect postal voting to benefit Republicans by facilitating votes from people in the countryside who live far away from voting centers.
So what actually gives?
Voting in cities is crazy. Like hours long wait times, you have to be very determined to vote. In person voting is much easier in less densely populated areas. Cities tend to be more liberal.
Depends on the local government in those cities. I’ve always lived in cities and never had to wait more than 5 minutes to vote.
