Answering TS.

What's the argument for challenging a guy with 78% approval within his own party?

Seriously? 78% isn't very good. If Obama gets 78% of the Democratic vote in '12, he's a goner, toast, history.

And what's the game plan? It should be compelling as hell to convince millions of people that the opinions they hold are, in fact, ignorant.

I really don't understand what this means. Millions of people thought Sarah Palin should be vice president. Millions of people thought George W. Bush deserved a second term.

What's the plan in the event of a loss?

As I see it, there is no "loss." If Obama continues on the course he's on now and faces Mitt Romney, he's going to lose. A primary might force him to adopt more popular positions (like say, not cutting taxes for millionaires, just as an example).

If anyone has any other suggestions to get him to do so, I'd love to hear them.

But if the economy is shitty in 2012, and the wars are still going on by 2012, and people still can't afford health care in 2012, and Wall Street continues to use the middle class as its plaything and people are still losing their homes -- they will blame the Democratic Party.

Any suggestions about how to mitigate that would be helpful as well.
