Republicans are excited about the long game, as their mid-term sweep has led to major gains in state houses across the country.
The obvious reason these wins are important is that 44 states will start redrawing their Congressional districts next year. Many of the states in the South now controlled by Republicans will pick up House seats and few of them will be inclined to treat Democratic incumbents well. The lines drawn next year could help cement Republican control of the house not only in 2012 but perhaps for the next decade or more.
I like the California methodology discussed in this article, redistricting by an independent commission. Rather than having redistricting handled by the legislature, organize an independant panel and require that a certain number of Republican/Democrat/Independant nominees all agree on the plan as drawn up.
