Some people just have a knack for doing or saying something at exactly the right time to get the maximum impact. Sarah Palin has taken that “knack” to a whole new level with her new video and the announcement that her “One Nation Tour” will be kicking off in Iowa on Friday.

She not only steals the spotlight from the other Republicans who are on the ground for the Iowa straw poll this Saturday just by being there, she totally knocks the wheels off Obummer’s bus with her one-line comparison between the two adventures: “Unlike next week’s Obama Bus Tour, taxpayers aren’t funding our tour…” Ba-da-BOOM!!!

Whether or not she decides to run is immaterial. Sarah Palin is a force of nature. She will defeat Obama in 2012. She has his number and she isn’t afraid to call it anytime, any place. He is so toasted.

I expect the trolls to start foaming at the mouth momentarily.
