The Great Destroyer

That's Balkin's title. Jack Balkin:

Although Ronald Reagan will still be regarded with fondness by the Republicans for generations to come, George W. Bush will have effectively destroyed Reaganism. The Republicans will have to start over with a different mix of concerns, agendas and appeals. This is George W. Bush's single greatest achievement. This is one reason, although not the only reason, why he ranks high (or low) among the country's failed presidents-- not only did his policies fail, but he also took the winning coalition that brought him into office down with him.
