During this November's election, only about 30 congressional districts out of 435 are considered competitive, in part because so many of the rest have had lines drawn favoring one political party over the other. In Maryland, for example, registered Democrats outnumber Republicans by more than 2-to-1, but Democratic members of the House of Representatives hold 7-to-1 majority in their delegation. Reform efforts are now underway in states like California and Arizona, which have created independent commissions to draw district lines. But in North Carolina, where a state that votes about 50-50 has 10 Republicans and three Democrats in the House, litigation is challenging the constitutionality of partisan redistricting.
