Been To Buy Blue Lately?
It's a real live blog that covers issues like Bush's FEC picks, the Koch Brothers acquisition of Georgia Pacific Corp and what that might mean in regards to environmental policy and Congressional desires to give our land to wealthy suitors in addition to being a resource to know if you're spending your hard earned dollars in a way that supports progressive causes.
They are also adding a lobbying dollars section (On goodie!)that I presume will be somewhat different than PSOTD does. Give them some feedback here.
