The MSM will do it very deceptively, without hardly any of the general populace noticing it.
Kind of like boiling a live frog, one degree at a time.
The Dems and the MSM are SOL no matter how they do it. Hillary ran against Obama the first time around. That wacky Chicago priest did a skit in which he mocked Hillary for thinking she was ‘entitled’. I know non-political blacks who could recite every word of that guy’s dramatization, and they even had all the inflections down pat. If any liberal thinks Obama can be eased out and replaced w Hillary they ain’t seen nothing yet. Part of their most reliable base will be in wholesale rebellion, and they won’t settle back down for a good long time to come.
