WaPo:

A group of wealthy liberal donors who helped bankroll the Center for American Progress and other major advocacy groups on the left is developing a new big-money strategy that could boost state-level Democratic candidates and mobilize core party voters.

The plan, being crafted in private by a group of about 100 donors that includes billionaire hedge fund manager George Soros and San Francisco venture capitalist Rob McKay, seeks to give Democrats a stronger hand in the redrawing of district lines for state legislatures and the U.S. House.

The effort reflects a sense among many top donors on the left that Democrats missed opportunities in 2010 to shape the redistricting process and contain the tea party wave that helped propel Republican victories around the country.
