I;'m not a 'loyal Republican'. Karl Rove is a 'loyal Republican'. George W. Bush is a 'loyal Republican'. I'm a conservative who left the Republican Party back in 2005 (after 30+ years) when Bush and the complicit RINOs in the congress were spending us into oblivion. What really did it for me though was when Bush, ignoring the overwhelming opposition to his proposed amnesty said, "See ya at the bill signin'." Republicans blow.
