I admire the courage and deep principles exhibited in leaving the party---but I have to agree with cal.
Giuliani, Arnie, Mehlman, Rockefeller Pubs, the Kristol "National Greatness" whackos, and Log Cabiners are cancers on the body politic.
They spring from the Everything-For-Us-Nothing-For-You wing of US politics (no different from Me Myself and I Democrats).
This cancerous growth can't be allowed to expand and infect the political system as we know it.
The Repub party got control of the Congress, the WH, and numerous state offices, for a generation BECAUSE of conservatives.
Everytime they try to win without conservatives---it's been a disaster.
In North Carolina, the only way to cross party lines is to be registered as an Independent. Since I will have NO VOTE in our Primary in May, the only way I can speak as a voter would be as a Democrat. I can at least help determine the next opponent in November. Make more sense now?
