The Cato Institute reports that Bush is ahead of LBJ in uncontrolled spending (PDF). Bush has completely failed to sell people on private accounts. So his only really big offering to the libertarian side of the republican party is pretty much a wash out. (The tax cuts don't count ... a tax cut is not a tax cut if you don't reduce spending. It is simply an intergenerational transfer of wealth.)
Clinton played the same game. Many have argued that Clinton sold out feminists and other central core elements of the Democratic Party to gain the center.
