So the bottom line is this: the Gallup poll indicates a pretty substantial shift in the partisan climate. But whether not it will be enough for Democrats to take over the House will depend on turnout. A turnout scenario like 2010 would not get the job done for Democrats, while 2008-type turnout very probably would. Some in-between scenario like 2004 (which is perhaps the most likely case) would make control of the House a coin flip.
Of course, well want to see whether Gallups figure is confirmed by other pollsters as well as how the numbers change over the course of time.[./quote]
Should point out that PPP had Dems at a similar 7-point lead in their last generic ballot poll.
Rasmussen also had GOP leading by only 2 points this week, even with their house effect.
