"Looking at Tuesday’s results from another angle, around two-thirds of the seats Democrats lost were held by members elected in the '06 and '08 elections. With a small handful of exceptions, nearly all of these districts are Republican-leaning, though most not overwhelmingly so. They represented the spoils of Democrats’ own wave elections. As currently drawn, many of them could theoretically be competitive in 2012, but Republican state legislative and gubernatorial gains could help the GOP use the forthcoming redistricting to fortify many of them.
New York, Ohio, Pennsylvania and Florida, where approximately one-third of Democrats’ overall House losses occurred, are potentially prime targets for this. With Republicans winning back both the governorships and state legislative chambers in Ohio and Pennsylvania, they will have carte blanche to strengthen the lines of the seats Democrats just lost through 2020."

"Furthermore, Republican state legislative gains in Colorado, Indiana and Texas could also strengthen newly-won GOP seats -- this is especially true for two new GOP prizes in South Texas. In California, the passage of Proposition 20, which removes redistricting power from the Legislature and awards it to a nonpartisan commission, couldn't have come at a worse time for Democrats, with Jerry Brown winning the governorship this week.
It's just hard to see how Democrats will be able to score the broad gains they'll need to win back their House majority any time soon.
It might just be another 12-year wait."
