There was an interesting "quick poll" on CNN.com a few days ago. I wish I had printed the results from when I saw the poll.
It basically measured what people really thought about the presidential campaign. There was one choice that said something like "I'm totally disgusted" which was getting around 37% of the vote.
I'll bet that voter turnout in the November presidential election will go below 50% again to the usual levels of non-participation. Lots of Republicans will be staying home and I'm sure that across the board people will be annoyed and bored by the final options.
