I’m not sure. Perhaps too driven by single-issue foreign policy to understand the wonder ramifications of potentially allowing Trump to win.
The thing they need to understand is that right now a vote for Biden is not a mandate for HIM or necessarily all of the policies that he is forced to carry out (and I mean forced by both GOP shenanigans (immigration stuff) and global strategic positions (Israel)) its a vote to stop the US being turned (even further) into a right wing shithole.
