Fineman posted an item at Huffington about the rising tide of Sestak-mentum ("Joementum" means something else).
Sestak has pulled up even with Pat Toomey here and it appears to be voter registration that's rocketed Sestak up in the polls -- mainly, declining Republican registrations.
Of course -- and not to beat this drum again so soon -- but Sestak has a world class television presence. Easily the best political spots I've seen in a while. They're hard-hitting, memorable, and to the point, but also fair. This is a combination that could be appealing to independent swing voters here -- and there are many.
