I approve of Cuomo. Though that's not saying much about the left-wing of the Democratic Party, I think parts of the Internet underrate Cuomo.
Who else has over 71% popularity? Beebe?
Probably not, I recall polling showing Beebe in the '60s. Heineman reaches similar levels at present, I think. Freudenthal and Hoeven both come to mind, but they both left office in 2010.
This is all presuming Hillary doesn't run (and she won't).
Hillary would be handed the nomination on a silver platter. And I don't think she'd be able to resist the temptation.
