Which only got 100x worse in the last 1.7 years. I've traditionally identified as a (D) but holy moly... now I'm partyless....

Should American women be allowed abortions? "I really have no opinion."
Is Trump a delusional psychopath? "Can't see any difference between him and Biden!"
Do these people really exist?

I moved to Europe in 2016, and America seems increasingly weird to me.
Here you have these two right-wing parties already, and you're like, "No, I need another right-wing party".
