Seems he is following Cornyn and the NRSC. Staying within the party and not reaching across the aisle to anyone.
How long will this last? Till the election is my guess.
McCain needs to be relieved of his duties cause he is one (of many) who have forgotten the oath they took when going into office. McCain is an embarrassment and a definite RINO extraordinaire.
It will last only to the Primary in August. Then, win or lose, it goes back to reaching across the aisle to “my friends”.
