One of the few arguments that Sen. Clinton's campaign ever made that actually made sense was an attack on Sen. Obama's then-high approval ratings vs. Clinton's then-lower ratings. The argument was that Obama had been relatively untouched by the GOP slime machine, and once they worked him over his numbers would be as low, if not lower, than Clinton's. It was plausible at the time, but I didn't think it was a sufficient argument for a Clinton candidacy.
It turns out, though, that even if plausible it was incorrect: Obama's approval ratings have not only held firm, they have improved over the last almost 11 months. Kos has the details.
I have been astonished to see the GOP playbook rendered totally ineffective this year. It's as if gravity itself is working against them, and I frankly couldn't be happier.
