Any cursory search of the voting record of Arlen Specter will make it plain to anyone with an I.Q. above room temperature that he will be at home in the Democrat Party. He has consistently voted for taxes, against liberty, and for expanded government. Take a look at it here.
If, and it is a very big if in my opinion, the Republican Party is ever to regain any sense at all of integrity it should be cleaning house. Not waiting for people along the lines of The Specter of Evil to resign. Leadership, real leadership, is so lacking among the Republicans that I think it is like Humpty Dumpty. Broken beyond repair.
My good friend Texas Fred has repeatedly called for a new conservative party, and I agree.
