People are wondering why Senator Biden isn't being the one to take Governor Palin on.  They want Senator Obama to rise above the fray and let Biden take her on.

Well - my theory is this.  They are waiting till the VP debate for Biden to do so.  He'll save his hits for that day.

Besides, Biden tends to slip with his words once in awhile and might blow it out of the water for Obama, so Obama's doing mild attacks just to keep her and McCain in sync while the accumulate the GOODS on her for the VP debate.

Go Biden!
