Redistricting in the US takes place after each decennial census and impacts the congressional district lines that will be used for the 2012 elections. Following their massive gains in the 2010 midterms, Republicans greatly strengthened their position to control redistricting in many states. Given that fact, I wondered what would have been the likely outcome of the 2010 and 2012 house elections if redistricting had hypothetically taken place after the 2008 elections.
The assumptions of this counter-factual are that A) Census numbers were effectively the same, and that B) national strategy doesn't change in unexpected ways. These of course would be different, but they are unknowable so I'm assuming they don't occur, anyway this hypothetical is really just a mental exercise for fun.
