In France’s 2002 election, socialists and other left-wing party members backed Jacques Chirac (who is, despite what many Americans think, on the right side of France’s political spectrum) in order to avoid the far right-wing Jean-Marie Le Pen from winning. That’s like communists voting for Bush.
Many in America seem unwilling to do something similar.
First, many conservatives are upset with the McCain nomination:
“I’m really depressed today because this is the first time that I find myself in a position that I will not work for the nominee (McCain),” said a caller to host Rush Limbaugh’s conservative talk-radio show on the verge of tears. (Reuter’s)
Second, Michelle Obama, on the possibility of Hillary winning, said:
GMA: Could you see yourself working to support Hillary Clinton should she win the nomination?
MICHELLE OBAMA: I’d have to think about that. I’d have to think about that, her policies, her approach, her tone.
GMA: That’s not a given?
MICHELLE OBAMA: You know, everyone in this party is going to work hard for whoever the nominee is. I think that we’re all working for the same thing. And, you know, I think our goal is to make sure that the person in the White House is going to take this country in a different direction. I happen to believe that Barack is the only person who can really do that. (Source)
It seems odd to me that people — Democrat or Republican — would risk someone they vehemently oppose (i.e., the opposing party’s candidate) winning because they didn’t like their own party’s candidate.
