Sorry, xzins, but there is no way that this was truly a D+11 election, and the GOP still keep up its numbers and control of the House.
First, I heard some commentators claiming it was a D+6 election not a D+11. I think Obama won by about 3 million votes. National election was about 60.2 million for Obama and 57.5 million for Romney. That makes it less than D+1 in reality. For every 57.5 republicans, you have 60.2 Democrats. For every 100 republicans you have 105 democrats. For every million Romney supporters you have 1,050,000 Obama supporters. If you multiply 57.5 times 1,050,000, you'll see it works out to 60.2 million.
Do the math: 57.5 is to 60.2 as 1 million is to X.
So, there's more than enough room there for Republicans to retain the House.
As for the House, Gerrymandering on both sides as made the body far more resistant to change. The democrats won the house level popular vote by a similar margin to Obama, but a lot of those votes on both sides are going to safe districts. Basically, with an earlier district map, Dems would have had a good chance there too.
Please...lets deal with reality.
Nope - even if this were a genuine D+6 election (like, say, 2006 was), the GOP would have lost the House, most likely, because that's what happened the LAST time we had a D+6 election.
Sorry, but the missing 3 million Romney votes are missing due to fraud.
I know that as a third party guy, you have a vested interest in trying to pin it on "Well, people just didn't like Romney enough to turn out" - but the problem is, none of the indicators suggested that to really be true. Even the Democrats were afraid they were going to lose.
