Experience - Off the Table?

I've seen it argued on the left, that by picking Sarah Palin as his running mate, John McCain has taken the issue of Obama's experience off the table. After all, she was a mayor of some podunk town in Alaska before becoming Governor of Alaska less two years ago. But they haven't thought this through. If the McCain campaign continues to hammer at Obama's lack of experience and they respond with, "Sarah Palin is even less experienced," the have actually conceded the overall debate to McCain. Turned on its head, one might ask, would you rather have an experienced Vice President and inexperienced President or vice-versa? This is another reason why the Biden pick looks so bad for Obama, it sets up an odd symmetry between the two campaigns, with McCain and Biden looking right-left versions of each other and Obama-Palin having their own uniques juxtapositions. (African-American vs. Woman, inexperienced senator vs. inexperienced governor.) The problem for the Dems is that the inexperience is at the top of he ticket. To use a physics analogy, its as if the heavier nucleus is orbiting the lighter electron, not the other way around upsetting the fabric of the universe.
