I must admit I had not yet considered that as a possibility. The Ross Perot strategy may be the only way Obama could be re-elected, but I think Bloomberg might end up drawing more from disgruntled Democrats than Republicans.
And as far as the minority demographics, Obama may have inadvertently cured many blacks of the romantic notion that a black president would solve a lot of societal problems. Hopefully his ineptness will result in minority voters no longer obsessing over skin color.
It could happen. (/Tenuta)
Without question, there would be some downside for Obama in a Bloomberg campaign. Bloomberg might be able to attract some Jewish voters that are disenchanted with Obama, but are unwilling to vote Republican. This could actually help Republicans in states like New York (oddly), FL and even PA & OH. Also, Bloomberg would have a very tough time attracting independent voters like libertarians precisely because he's such a avowed Nanny-Mayor.
"Hopefully his ineptness will result in minority voters no longer obsessing over skin color."
I hope that's possible, and very recent polls indicate that it might even be possible. Obama - who for the last 19 months has enjoyed black support approaching 95%, slipped to as low as 88% in a few polls in the last couple weeks. I don't know if that disapproval would actually translate into Republican votes, but it might suppress minority turnout, which would be the next best thing.
To be clear, I'm not saying Obama is guaranteed reelection, I'm just saying he's going to be MUCH harder to beat than some people - in their near current euphoric state - understand.
