If you look back at the 1960's in the United States, and if you think that more good was done than harm, you are probably a Democrat. If you think that more harm was done than good, then you're probably a Republican.
When I first came to Washington in the 1960s, even at the height of the Vietnam War, until the end there in '68 there was a certain climate of cooperation.

And I just hate it.
