Your theory may be right....and non Democrat who is showing a pulse might be any Democrat. In 2008, we saw both McCain and Obama run against BUSH...and no way any Republican could run away from Bush harder than any Democrat.
I think it’s likely that both party nominees are going to “run against Obama” in ‘16. No way any Democrat wins that....or almost no way.
But I don’t think Jeb is smart enough to understand that. I think he really thinks his moderate mushy way is what the country wants, period. I doubt he’ll run hard against Obama.
This is who we need as a candidate...
