McCain is an asshole.
President Trump Makes A Case For Why McCain Should Retire ... Of Be Re-Called
He said mean things to Trump
That's the entirety of Trumps reasoning
I'm on record, somewhere on this cite admitting that the failure to repeal by congress is proof that their previous repeal votes was bullshit grandstanding.
McCain is part of that, and he, with all of them, owe an explanation to his voters.
Senator McCain has already and repeatedly stated a reason. Just because you doing pay attention is no reason to lie about the fact.
What was his bullshit reason?
