@MaierAmsden No opinion. There's a lot of blame to go around, but the job of the candidate is to get elected, it's never a good idea to make your voters step over the dead bodies of children, and you go to battle with the electorate you have not the one you wish you had.
You can be mad at 10M people if you want to, but they weren't running for President as a Republican despite the Dem base being... well, not Republicans.
