Let me say this. The Democrats have virtually no shot of winning the House. They have less than 1%. Let's look at the experts and how many seats they currently see as Likely/Safe Republican
How is that for a consensus? If Republicans win their likely/safe seats, the Democrats have to almost sweep all the seats remaining. That's illogical. If they were going to win that many seats, more of them would be lean/likely Democratic. Here are the seats that lean each party:
This isn't a knock on the Democrats. It's a compliment to Republicans. The states are so gerrymandered, it'll take a big wave for Democrats to win the House. If the Democrats had been gerrymandering they'd have a good shot.
I think the Democrats would need a D+8-10 to take it, if not more. In 2006 they had a D+10 or more, usually D+13-15. In 2004, it was D+6-9 early in the year but ended D+2-3. This cycle has been a toss-up with no poll being bigger than D+4. I can't imagine a scenario, even an Obama landslide, that's going to result in Democrats taking the House.
