So your point is that an ambitious man like John McCain:
1.) Who had been seeking the Presidency of the United States for many years ....
2.) Who would have considered the Presidency as the crowning glory of his family tree ....
.... Shot his Presidential ambitions in the foot and picked a woman that very few people outside of Alaska had ever heard of before just to "undermine the conservative movement"?
Do you have the slightest clue how totally irrational and tin-foil-hat that thought process is?
Even if such irrationality was present in John McCain's brain, what is your point?
That Sarah Palin was such an obviously flawed candidate that picking that unknown woman would have "undermined the conservative movement"?
