Name the President/VP ticket that you think can beat whoever the Democrats elect? I think a Cruz/Carson ticket would take enough minority votes to win. Would love a Trump/Cruz or Cruz/Trump card but that's never going to happen.
Donald Trump/Susan Rice, she could go on and on about how Hillary threw her under the bus that Sunday morning and ruined her career. Plus she's a woman. Plus she is black. And the other thing.
Or how about this scenario...the GOP and Dem brass decide that they will ignore the populist choices of Sanders and Trump and nominate Clinton and Rubio and then you have both Sanders and Trump running as Independents.
Trump/Sanders would destroy Hillary. Unlikely, but it would not surprise me at all to see him choose someone left of center. It would be a smart move. Bridge building, and all that good stuff.
