I thought Cruz's "ask President Dole and President Romney" attack was distasteful. Not so much for John McCain, but still, the point stands.
This made me think of something I've always wondered - why is the GOP so disdainful of its history to an extent that Democrats and liberals never approach?
It amazes me how these people can nominate someone one year and then express open, unadulterated contempt for them just a few years later.
Compare the way the Right and the GOP treat George H. W. Bush - a one-term president who was far-removed from hardcore conservatism - to the way the Democrats and liberals treat Jimmy Carter - also a one-term president who was far-removed from hardcore liberalism.
Democrats don't openly mock failed candidates like Gore and Kerry (or even low-hanging fruit like Dukakis) while the Republicans seem to want to pretend every president and presidential candidate other than Ronald Reagan never existed.
