I disagree. I think turnout will be low (51-52.9%). Both candidates have support but there is a general lack of excitement for them.
I agree with your analysis.
I would add that the percentages used are based on Voting Age Population. Since much of that population is ineligible to vote (alliens, convicted felons whose civil rights have not been restored - in most states, and people not registerd - in most states) the actual percentage of eligible voters voting is significantly higher.
I think I disagree. The people were fat and happy back in 2000, so turnout was low, but not as low as previously. This year people aren't quite as fat or as happy, so they'll want to "do something" and since most people actually seem to believe their personal conditions are affected by the identity of the president (and for some it is arguably true) they'll vote. I voted 53-55 percent, about the same as last time.
