Coming into this thread late....
It'll be Clinton/O'Mally VS Bush/(Christie, Ryan, or Rubio)
There are no southern Democrats to put on the ticket with Hillary, so it doesn't matter where Hillary's VP candidate comes from. Elizabeth Warren is too far left, and it's not quite time for two women on a presidential ticket.
Untill a Republican candidate starts polling within 5 points of Hillary, she will be the next President...especially if the Republicans go on about gay marriage/contraception/abortion in the mean time.
The GOP will also need to create legislation that Obama will sign, ot they'll be blamed for nothing happening in Washington, still!, in 2016
OK, try this insteadL
Hillary will not run as her negatives inside the Democrat Party are too great.
Dems will push Warren as Obama perfected. A Warren-Holder ticket will hit all the Dem strongpoints.
It will be utterly overwhelmed by a Walker-Cruz ticket, pitting the accomplished well spoken against the inexperienced radicals.
The GOP will work cleverly with dissident Dems, unhappy with their party's electoral performance, and come up with legislation that will easily get 2/3rds votes to override the veto, making Obama look like a blustering fool.
