I’ve been gaming on EndeavourOS for over a year now and have had the opposite experience. All my games work great in Steam with Proton. Granted I don’t play modern AAA shooters or League of Legends which goes out of their way to use bad anticheat that doesn’t support Linux. Only one time I had a game not start right away and all I had to do was install .Net for it or something which was also very easy.
I think the simplest answer is that Trump “owns the libs” and that’s enough to make people who don’t follow politics vote for him. Hillary ran a pretty shitty campaign also. Trump has definitely gotten older and way more whacky so I guess we wait and see what happens in November.
