This Roll Call article (paid subscription required) talks about the upcoming controversies over 527s at the FEC (see my many blog posts in the past week on this subject below), with a focus on Democratic FEC commissioner Scott Thomas, who appears to hold the balance of power on this issue. Today’s issue also features 527s Thrived in 2003, Two House Commitees Report Robust Fundraising, and this column by Stuart Rothenberg on 527s and MCFL.
