please, reread your post because I think that you wrote “center-left” when actually meaning “center-right” in many of your last few statements.
Oops - you're right!
Not sure how but there must be a Freudian slip in there.
As for the balance of your post, I'm not sure what you are trying to assert.
If the nation is "center-left" (and I mean precisely that this time), then Obama's leftist agenda will be generally well received (Assuming the MSM doesn't turn on him and suddenly go conservative). You don't need to pave the way.
BTW - You (and Cyclo) need to reread the sacred text of the Prophet Dawkins. Assuming that something as theoretical as a "meme" exists, then it's pretty hard to accept that the notion that America is a "center-right" nation is anything more than a would-be meme.
You may be wise to attempt to crush it in its infancy but are overheated in railing against its established propagation.
