More unfortunate news for the Democrats. From Gallup:
Since the vast majority of voters majority of voters always vote the same way, what frequently determines elections is not how people vote but which people vote. Note that in 2004 the Democrats enjoyed a 17 point advantage in enthusiasm. Dubya still won. The gap was much greater in 2008. Obama wins.
So what do the Gallup numbers mean right now? I can't tell because I can't know whether the numbers are accurate. Too many things changed over the last eight years and pollsters can control only for some of them.
What we can say is that if these numbers are correct, written in them is doom for Obama and for a lot of Congressional Democrats.
