Here is an article from the Daily Press in Virginia about their attempt at reform:
Self-preservation drove the House Republicans to torpedo the measure that would have created a bipartisan panel to revise General Assembly and congressional district boundaries in 2011, following the 10-year U.S. Census cycle. They know, everyone knows, that their party’s control of the House of Delegates is far better assured by preserving safe, gerrymandered districts, customized according to previous election results to cluster predictable voters for predictable majorities. By one count, of the 140 House and Senate seats on last November’s ballot, only 17 amounted to real contests. Actual competition in elections might upend the imbalance.
