A couple of follow up points:
1) I completely agree that Dems need to do a better job on a statewide level in several places. In certain states I don't think there's a structural problem and would expect a bounceback. Remember how Tim Pawlenty was supposed to turn Minny red after his two terms? So, states like WI, MI, NV I'd expect to bounce back. I share the concern about a place like Florida where the state party seems atrocious and has been for years, no small wonder given that it yielded the world Debbie Wasserman Schultz.
2) Having said that, my proposal (well, I didn't come up with it) eliminates the wait for a 10 year state legislature reclamation project to bear fruit. Already states like CA, AZ, IA have independent commissions. The easiest way to get more is a ballot initiative. Lets get that done, pronto.
3) Lastly to uno's point, we're not talking that many states. One, two and even 3 district states really don't lend themselves to too much mischief. ME, NH, VT, RI, DE, ND, SD, KS, NE, MT, WY, ID, HI, NM, AK, WVA = 16 states where this is irrelevant. Of the remaining states AZ, CA, IA, NJ and WA have an independent process to some extent. In addition Florida has a law that incumbent protection can't factor into drawing the lines. So, lets pick and choose our battles (and in fairness Goopers should be pushing for this in Illinois). Really you're after 5 states (PA, WI, MI, OH, VA) to start with.
