I haven't read any of those blogs but that is exactly what I concluded when the leak of Biden was out there but unconfirmed. There is really no other rationale to choose a smart alecky, verbal gaffe-proned, 30-year + DC insider from an insignificant state. The obvious choice would have been Hillary (the equivalent of Kennedy choosing Johnson) but even I can understand why she wasn't chosen.
Still Clinton would have been the rational and gutsy choice but instead will now be sniping from the wings and costing Obama 5 to 10 points in the General. That is unless the Dems are demoralized by the choice of Biden to the point that there indeed is a flip of delegates in the next few days.
I'll wait until Obama gives his convention speech before I truly rejoice.
SIMPLE, Because THE VOMIT FROM HELL said NO to an oSama/ Hitlery ticket!!
