RE: "That's to say, didn't we put him where he is? Don't we share some responsibility for his policies and behavior?"
My interpretation of voting patterns in this election indicate that two groups put him over the top: The underclass and the super wealthy. Why? Because the underclass wants free stuff, and the super wealthy (Buffet/Gates, et al) are immune to Obama's income tax policies. The upper-middle class ($200,000 - $500,000) will take it in the a ss.
