MIKE BARNICLE, MSNBC:The next 48-72 hours will be pivotal as well as deeply interesting with regard to Sen. Sanders, in Burlington, VT today resting up at home -- God bless him.

Clinton unqualified, or is he going to revert to the issues, and stick with the issues.
We're going to find out who Bernie Sanders is.
