First, scrap the filibuster in the Senate. Second, stop gerrymandering. Four states have already handed control of redistricting to independent commissions. California did so in 2010. Between 2002 and 2010 the state’s House members held on to their seats 99.6% of the time; in 2012 a quarter of them retired or got the boot. The reforms also moderated California’s state legislature. Once dominated by doctrinaire Democrats, last year it rejected 39 out of the 40 bills that the Chamber of Commerce said would kill jobs. One day, with luck, computers will design voting districts without taking party preferences into account.
