It seems our Senators have a thing or two learn from their home states when it comes to campaign finance reporting: 31 states currently require mandatory electronic reporting ("e-filing") of their elected representative's campaign finance records -- a leap above our Senate, which has failed to pass no-brainer e-filing legislation for over a decade. Sunlight conducted a review of the current state of similar filings in the states (see chart below), and the results are pretty surprising -- in a great way. State governments across the country -- 92% of them, in fact -- require at least optional, if not mandatory electronic filing for both houses of their bicameral legislatures.
