Isn't it amazing how the election results this year changed the redistricting potential in exactly zero states, as far as I can tell?
Yup, that is remarkable, but to state the obvious there are still two elections before the next round of redistricting, so the playing field is hardly set yet. The two major battlegrounds I'd say are Michigan and New York. Those are the big states with maps that currently favor the GOP where Dems have a good shot at unified control by 2011.
