You think the Democrats are going to win the WH after two more years of Obama?
It depends on who the Dems and Pubbies actually end up nominating.
I don't think Hillary will be their nominee. The faction that derailed her last trip to her coronation will try to do the same, if she runs. Many of the 'consultants' from the Pubbie side claim 'it is her turn'. Her turn? That only happens on the Pubbie side. Look for the Dems to field another charismatic, articulate, youthful person.
