“Trump had rather have Biden re-elected then to unify the Republican party.”
Now that is too funny. Do you think the Republican party will unify behind Trump if he is the nominee?
I bet you can answer that question by checking to see what other nominees have signed the pledge that Trump has chosen not to sign.
Of course they will. They've done so twice before.
Trump's problem won't be the GOP unifying behind him. It'll be all the independent and swing voters who don't.
