This man cannot be permitted to be veep. Homosexuality is a mental disorder and can't be tolerated in a position of power. Worse, since he's hiding it, he can be blackmailed. Even worse, he may simply "come out" once he obtains the power...
Hello John McCain, Please dont pick a Three Dollar Bill for your VEEP! We are a party of Family Values and Strong Morals with No Excuses, Period! Governor Crist will make an Excellent Ambassador to Thailand:-)
