All those gains are hugely significant in redistricting. When the 2010 Census results are announced next month, the 435 House seats will be reapportioned to the states, and state officials will draw new district lines in each state. A nonpartisan commissions authorized by voters this year will do the job in (Democratic) California, but in most states it’s up to legislators and governors (although North Carolina’s governor cannot veto redistricting bills).

Republicans look to have a bigger advantage in this redistricting cycle they’ve ever had before. It appears that in the states that will have more than five districts (you can make only limited partisan difference in smaller states) Republicans will control redistricting in 13 states with a total of 165 House districts and Democrats will have control in only four states with a total of 40 districts. You can add Minnesota (seven or eight districts) to the first list if the final count gives Republicans the governorship and New York (27 or 28 districts) to the second list if the final count gives Democrats the state Senate…

This will make a difference not just in redistricting. State governments face budget crunches and are supposed to act to help roll out Obamacare. Republican legislatures can cut spending and block the rollout. “I won,” Barack Obama told Republican leaders seeking concessions last year. This year he didn’t.
