As I write this, cable news is flashing that Hillary and the Man Who Would Be King are meeting face-to-face.
My observation is that Barack Obama has always taken the path of least resistance. Hillary would be the easy choice here, just as joining a high-powered and somewhat wack black church in Chicago was, as was accepting the support of William Ayers and his considerable Chicago network, Ayers being the ex-terrorist who helped bomb the Pentagon and now masquerades as a respected academic.
The no-brainer choice [and I don't mean that in a bad way] would be to select Gov. Phil Bresden of Tennessee or Gov. Ted Strickland of Ohio. Both would give Obama considerable clout in the Caucasian Belt, which leans Republican, and where Obama struggles even against Hillary.
The smart choice would be the best man for the job---Evan Bayh, son of the legendary Democrat Birch Bayh, a staunch Hillary ally, and himself both a two-term governor and now senator from Indiana, a Republican state and one with a lot of white people.
Two birds, one stone.
