POTUS elections hinge on the economy.
Baraq loses any 2-way matchup that I can envision based on 10% unemployment, $4 gas, and surging food prices.
His only hope is a Clintonian plurality win. There are two scenarios for this:
If Mittster is the nominee, Im very sure there will be a Tea Party candidate also.
If Palin is the nominee, there will be a Soros backed MSM promoted independent candidate.
One would think that'd be the case, but Obama has a cheerleading mass media that is hugely in his corner. Like it or not, people listen to what old media say. Their daily diatribes against whomever will be the GOP nominee, plus constant accolades about Obama will take their toll on any opponent Obama faces next year.
Not to say it's impossible to beat him, but it will be extremely difficult.
