New PAC will challenge Obama's redistricting efforts

Background: Barack Obama has made redistricting a post-presidency focus, launching the Democrat National Redistricting Committee along with Eric Holder, which has raised $11 million in its first 6 months. The Virginia elections proved that Democrats' strategies for wining back state legislatures are effective.

Big picture: District lines have generally favored Republicans for the past 20 years, and the GOP has been accused of gerrymandering along racial and cultural lines, with several cases being challenged in court. Democrats' victories in Virginia state elections earlier this month were crucial and will fuel their future efforts to gain legislative power (and therefore redistricting power) in the states, which could be a devastating scenario for the GOP.
