Since Ronald Reagan, not nearly enough things have gone Right for Conservatives.
Government expanded during the Reagan administration. Abortion didn't end during the Reagan administration. Illegal immigration didn't end during the Reagan administration. Public schools didn't improve during the Reagan administration. Are you willing to say Conservatism died in 1980?
Even Reagan did things some conservatives didn't like. People critical of Bush's amnesty for illegal immigrants seem to forget the fact that Reagan did the exact same thing during his presidency.
And as for growing the size and scope of government, Bush shrunk government at its most intrusive point: He passed the largest tax cute since Ronald Reagan's.
