A person who rabidly supported Hillary Clinton for the '08 presidential nomination, but was unable to accept her loss, and has switched to the Republican camp; because, if McCain wins, Hillary might have another chance in 4 years.
The Hilldogs are willing to flush America down the toilet for 4 more years because they're bitter about losing.
