Yes, talent often makes up for experience - as Einstein once said about the old "9/10ths prespiration" adage: "A touch of genius makes up for all the hard work in the world".
And there is a deep mythos in the USA about the benefits of a maverick steering his or own course based only in belief. But we've seen where this takes us when we look at national policy. We've seen where belief that Hussein has WMDs lead us, how the belief that those turned over by Pakistani police were "the worst of the worst" allowed us to torture, how the belief that "liberals run the government" allowed violations of the civil service law to become the norm, how belief in christian creationism leads to an ignorance of science and the list goes on.
If anything, Palin is most like George W. Bush - evangelist, creationist, anti-science, anti-intellect, prejudiced (but in an acceptable way), obdurate and overly convinced in their own righteousness.
As for McCain being willing to go against his own party - that may have been true in the past, but since his run this time around he has largely changed on this issue.
- McCain is 100% with the GOP on resource management
- McCain is 95% with GWB on all major issues
- McCain is 100% with the GOP on the military
- McCain is 100% with the GOP on invading women's bodies
- McCain is 100% with the GOP on writing discrimination into the US Constitution
- McCain is 100% with the GOP on tax policy.
So I'm curious, where is McCain "not afraid to go against his party"? In creating McCain/Feingold - the law that allowed Swiftboating?
