The SUSA polls show that BHO does even better when some of the likely VPs (not HRC) are added to the equation. They show that Barack has some very good options, while McCain - not so much.
It's almost worse news for Hillary, since Edwards (and presumably Webb in VA or Richardson in NM) adds some real momentum to the Democratic ticket, even in the states that Hillary uses to make her case (OH, PA).
It seems that HRC (and Bill) have waited too long to make their case for the VP spot. Who would want them now that they've gotten so nasty?
