McCain says his thinking and choices are not about him, they are about America. Well, in picking Sarah Palin as a running mate he has turned this thinking upside down. This is clearly a grab for the disgruntled Hillary clan and clearly panders to the neocons. Let's picture a day when McCain is gone (sorry, but you always have to think about this) and she becomes president. Does that scare you? It scares me to death, even if she is a fine woman, great mother, etc. Let's picture her on the telephone with Putin. "Hello, Mr. Putin. How are you? How is the weather in...uh, er...where you are?" Or better still, "Hello, Mr. Hu." Aside, "Who is Hu?"
Now compare that to Joe Biden.
This shows a lack of judgment on McCain's part. And being president takes judgment and the ability to look further than your nose.
