Neither do conservatives.
No doubt there are the “conservatives” that supported Bush in 1980 versus Reagan who don’t believe in Limited Constitutional Government. Those “conservatives” don’t like Ron Paul. Those are the same “conservatives” that worked for the Democrat Scoop Jackson in the 1960s and/or 1970s, and joined the Republican Party in the 1970s and 1980s. They support Big Government and they call their policies “conservative”. See: Bush.
