I don't know of a time in recent memory with "even keeled" republicans (at least beyond the Primary). Romney and McCain would be the last I'm aware of.

I'm confident that I've heard both sides saying exactly what you're saying though... and I remember many times that "the end of democracy" was around the corner.... and if such-and-such wins a race war is going to break out etc.

The rhetoric and post-election-dooming is always the same regardless of which side wins.

I pretty firmly believe that things like the economy, incumbents tendency to remain in power, and a party switch after hitting the term-limit are the biggest factors. What people actually say once the primaries are over just doesn't matter to most people. People will cherry-pick what they want to hear.
