States See Growing Campaign to Change Redistricting Laws

This seems to me to be good news. Of the problems with current redistricting laws in most states, here are two of the most significant:

In the 2004 Congressional elections, only 13 seats in the House changed hands, and four incumbents were defeated in the general election. In 2002, 82 percent of the races were decided by a margin of 20 percent or more, Common Cause said....
The second problem is the extent to which redistricting contributes to polarization, as map-drawers cluster like-minded voters into the same districts. That makes it less likely that a candidate will work to appeal to swing voters. In those districts, the main worry for incumbents is often not a general election but a primary, because Republicans are more likely to move to the right, and Democrats to the left, to protect themselves.
