We are BARELY majority Republican, and yet people here are upset that the White House and Congress aren't majority Conservative. The country is not majority conservative. I read somewhere recently about estimates that Liberals - Moderates - Conservatives are something like 20% - 50% - 30%. That sounds fairly accurate.
Jean Francois Kerry wasn't a liberal -- he was a nothing. Just like Bill Clinton post-1994, he would have governed as the kind of president who none of his supporters would have recognized.
