Also: GW Bush’s “re-election below 50%” is misleading. Gallup was doing weekly reports at the time: He was at 51% on Oct. 22, 48% on Oct. 29, and 53% on Nov. 6th. He was re-elected with 51%; his re-election numbers were entirely consistent with his approval ratings.
As long as the Dems believe below 50% is good enough, I’m happy with that, knowing it is very likely NOT good enough ;)
