Whatever point you are making is irrelevent.
Independent support for Obama is down considerably.
The most comprehensive polling done recently, that of Rasmussen, shows those claiming to be Independent to have risen to over 30%. Those claiming Democrat affiliation is at 37.5% and those claiming Republican affiliation is just over 32%. The spread between Democrat and Republican is at its lowest level since the end of 2007. This spread was even more narrow over the summer months, but has since risen back to pre-summer levels.
It is the loss of Independents that will hurt both Obama and the Democrats most if they cannot remedy this trend. It's the Independent voters who decide elections.
Obama is losing Independents.

And your claims are irrelevant unless the stumbling republicans see a corresponding increase in support from independents.
You see Obama has the advantage of getting to run against whatever stiff the republicans happen to nominate. Unless the Independents are willing to throw their support to the republican stiff, Obama's standing with Independents is irrelevant
The loss of Independent support, and the corresponding favorable margins for the Generic Ballot for Republicans since June of 2009 (the same time Independents started to pull away from supporting Obama) would indicate the setting is being primed for just such a possibility.
It may happen - and it may not, but the change in outlook is remarkable. The Republicans have gone from no chance, to good chance in 2010 - which of course, is the basis of this thread.
2012 is too far to project accurately yet - though I would agree Obama is still the likely winner if those elections were held today - but the margin would be much tighter than just six months ago...
Hillary could beat Obama today.
