According to Leonard Peikoff:

"Ayn Rand once said: If you hear something bad took place in Washington, the Democrats did it. If you hear that something godawful horrible took place, the Republicans did it. And it's true. Time after time Republicans have opened the door to the Democrats and made possible a situation which would not have otherwise been possible. The Republicans passed the Sherman Antitrust Act. Hoover opened the door for the New Deal. Bush the second started all the business things and treasury policies that opened the door to Obama's behavior. Who knows what the next Republican president will open the door to. All we know is he won't open it as wide, as fast."
