He has probably noticed that the right wing propaganda machine has been working. The lies coming from the radical right via Fox News, emails, the internet and everywhere else has been effective in allowing the extremists to wag the middle line conservatives to their will. After all, even today there are people who believe the lies that Obama is Muslim and not American.
There used to be a time when there were differences between the republicans and the democrats, but they met and compromised and got things accomplished. The mainstream in both parties were along the middle, not the extremes. When either side lied, or stretched the truth, it was called out. Today, with all the lies that have been perpetrated by Fox "News", all those insipid radical right wing talk show "hosts" and the constant barrage of false emails sent out, is it any wonder that so many are having difficulty separating the truth from reality. Sadly, it is too obvious that the republican party has been hoodwinked by the huge propaganda machine that is the Koch brothers and now the common sense republicans are caught with no place to go. The typical response from the now disillusioned republican mainstream is that both parties are corrupt, when it is obvious that the republican party is the one that has gone off the deep end. This response is normal, I think, for someone who has suddenly found himself/herself in a party that no longer corresponds to their core political beliefs and the other party never did, either.
I think the Koch brothers and the lying right wing extremists talk show "hosts" propaganda machines have been hiding under the first amendment long enough. It has been said that America will fall from within. These guys are the problem and as far as I am concerned extremely anti-American.
