With Sarah it's, “Obama talks like an incompetent leftist and he acts like an incompetent leftist, so he's an incompetent leftist.”
Apparently Krathammer used all the deductive reasoning he learned at Harvard and it took him three years to come to the same conclusion Palin did in three seconds.
Where Krauthammer is wrong is Obama is not intelligent, as most Leftists are truly not intelligent. Rather, they are delusional in never admitting the failure of their ideology. When the implementation of the their policies produces a negative and destructive effect, they will never conclude the ideology is at fault. Rather, their only answer is to implement even more of their delusional beliefs.
Obama is the poster child for how blind and stupid the entire ideology is. "Incompetent Leftist" is spot on.
