Because McCain is a plant. Like all plants, it is required that sometimes he exhibit behavior that makes you think he actually is what he says he is, and isn’t a plant. This is calculated. But when the time comes for something important to take place, he is called upon to do what he is there to do - advance the agenda of the left.
OK, maybe this is tinfoil hat stuff, but his behavior too often makes this scenario plausible.
I believe you have the gist of the quandary about McCain and other professing conservative politicians. I wonder how many of these types have had slush funds along with a host of other bought and paid for ‘citizens’ in banks like the Vatican Bank.
RIGHT ON! This also is what 95% of the (R)s have & will continue to do.
