Matt Stoller tells us that George Soros gave $500 to Kevin Powell who is running in a primary against Ed Towns in New York's 10th Congressional District (scroll down for map).
Not only is Towns a cosponsor of HR 676, he sits on the critical House Health subcommittee, so his support is crucial for getting this out of committee.
Powell also supports single payer and has a very clever presentation that explains the concept.
I don't know the issues in this race, I hope that netroots stays out of this and permits Brooklyn Democrats to judge for themselves.
