Note that her ready to be President numbers have dropped substantially from Friday. Now its 48%-29% no, a 19 point deficit compared to a 2% one on Friday. That is the number that is going to drive the McCain-Obama numbers, not Palin's favorables. People seem to view her as a nice lady who is maybe a bit too busy to be Vice President.
Be careful. It does not necessarily follow that because someone is unready to be president that they are also unready to be vice president. It would be hard for her favorables to be as high as they are if people didn't want her serving in any capacity.
Count me as one of the 48 percent who doesn't want her as president but thinks she'd do a fine job at being number two.
