Now is the time, I agree. If you are betting Obama, do it now. I think this is as low as its going to get. Basically we are 1 week from convention bonus, and IMO Mccain numbers are going to go down from here on out. The polls still out are from Sept 7/8, which show the bonus from the convention. To assume that this is tread, is incorrect.
Forget about your political affliations. This is Obamas race to lose. He the numbers on his side.
I don't think Obama losses any of the Kerry states, except for maybe New Hampshire. The two states which Mccain has chance taking from Dems, is Michigan/PA. However even after the convention bounce, its still +2 lead for Obama. These states, which traditionally are Dems aren't just going to swing +3 like that. Add to the fact Dems outnumber Reps in these, alot of new registration is going in these states (400,000+) in Michigan, Florida and North Carilona. It's VERY unlikely these two states turn Red, given that Mccain has to allocate his resources else where.
That brings us to Florida/Ohio/Virginia. If Mccain loses any of these, basically its game over for him. Florida is basically tie (again 400,000 new registered votes which majority are probably dems). Mccain has slight edge in Virginia/Ohio. Obama doesn't even have to win any of these. He just has to stay competitive that Mccain is left to allocate almost all his resources in these states.
Then you have the traditional red stats in NC, Indiana, missouri, and south dakota which are running close. I don't think Obama has any chance in these states, but typically it would be considered a gimmie, which isn't anymore. So more resources need to be allocated.
Assuming Mccain has kept Florida/Ohio/Virginia and the traditional states, that leaves Obama with 252. Add Iowa which is given, its 259.
That means he needs 11 from Nevada (5) Coloroda (9) New Mexico (5). He is currently winning in 2/3 of the 3, and he was winning in New Mexico before the convention (down about 2 points). If its a tie 269, I think congress votes, which would mean Obama wins. So all he needs is 2 out of the 3. And that is ASSUMING everything goes well for Mccain in regards to those swing states.
Math is against Mccain. The only scenario I see him winning is total blowout due to big Obama gaffee or big revelation.
So take Obama before Monday, because I think the polls will start going the other way after the convention bounce.
