High Approval Ratings do Exist!

I was reading some GOP talking points on last night's election results. This one I found the most interesting (and not particularly helpful for the Republican):

Incumbent Democrat Governor Mark Warner's approval ratings are at 80% (according to The Washington Post), an enormous advantage for Kaine.

80% ?!?! I knew Warner was popular, but I didn't realize he was that popular. Can he work his wonders on the presidency? I'm so used to seeing approval ratings that are at 39% (Bush) and a whopping 28% (Ah-nold) that 80% is just amazing!
