You see what's going on there, don't you? Why would our Democratic President do some high-profile hobnobbing with the Republican Governor that Democrats have targeted with protests and a recall effort for the past year, even as the recall election is still pending?
I'd say Barack Obama is looking down the road to November, making some predictions and hedging his bets. He doesn't want to be bogged down with seeming connections to the most belligerent and left-wing elements of his party. He wants to stand separate and independent, and ready to be loved by one and all throughout the lovely swing state of Wisconsin. A walk with Walker is a fine readjustment to the political center. Well played, Mr. President!
Obama wants the recall effort to fail, no?
