Via this tweet, we just discovered that the President’s budget proposes that the Senate should be required to electronically file their campaign finance reports.
In this document, you can find the following section:
The Budget proposes that Senate Campaign Committees be required to file campaign finance reports electronically with the Federal Election Commission, in keeping with the reporting requirements for all other Federal political committees. This measure would save the Commission at least $430,000 annually by reducing costs for manual data entry and will promote transparency by expediting the process by which the reports are made available to the public. The Commission is authorized to submit, concurrently, budget estimates to the President and the Congress. The Commission endorses the President's 2013 request.
If only the Senate were so easily swayed by reason.
