McCain viscerally hates conservatives and wants to provide his buddies the democrats with permananent voting majorities, just as he wanted to get democrats unlimited campaign funding while limiting republican campaign funding in his Campaign Finance Reform law. He went apoplectic when the Citizens United decision came down, gutting his signature legislation.
McCain is nowhere near any description of a constitution loving republican and he has managed to take Jeff Flake along with him on the ride to permanently castrating the Republican party. JMHO but I believe that McCain was wrapped up and sold on world socialism in the Hilton. He has brought his desire for one world government to Flake and convinced him also. His moves are not out of blindness but dedication.
AZ hates conservatives too. Look at their awful voting results for so long now. Must be overrun still by Californians.
