Btw, John McCain showed he wasn't fit to be president, and was possibly suffering from the first stages of dementia when he thought Sarah Palin would make a good running mate.
I agree with most of your post.
John McCain, in my opinion, was not fit to be president, not because of Sarah Palin (the senator did not select, Palin, his staff's top strategist did) but because he was not intellectually up to it. I don't know about the onset of early dementia....he's certainly made some boo-boos in his opposition to Obama's agenda, his refusal to accept reality that he lost to Obama in '08, plus he's too warlike. I have never known one so persistently eager to go to war as McCain. At 72, then, and running for president almost 6 years ago, McCain was content to sit back and let his political strategists think for him; they strategized bringing in a woman, who for all outward appearances, a successful governor, would counterbalance the Hillary effect with women. At first, the attractive Alaskan governor was refreshing, speaking from prepared text, even causing slippage in Obama's poll ratings, until a little later in the campaign she proved a non-highschool graduate knew far more about politics and the world in general than she did (the katy couric interview).
Not only did Sarah Palin hurt McCain politically, she is still at it, damaging the Republican brand, but is now defined as a stubbornly ignorant petty-minded Tea Party racist who appeal to the worse traits in our kind.
