So how is the betting market treating the apparent tightening?
By putting more money on Obama.
Current odds are: Obama $1.11 and McCain $9.80.
If you think that McCain can win then nearly $10 is an amazing price and you should load up.
McCain's only chance seems to be that young voters do what they've always done and suffer a huge, debilitating dose of apathy on polling day and stay home, based on the assumption that polling companies are over representing young people.
One assumes that blacks will vote in record numbers and that may prove decisive though I think that the Hispanic vote may trend back to McCain.
All in all, it's looking ugly.
I've got my fingers crossed that the Democrats don't take the Senate.
That would be a huge problem for America and, by extension, for the rest of the world.
