Barack Obama once confessed to politics’ original sin but has yet to atone for it. He now has an opportunity to do so.

Well, Mr. President, it’s time. You have no more campaigns to wage. With a little less than 12 months left in the White House, you have the opportunity to atone for exploiting a system that you have deplored in words if not deeds. You can restart the engine of reform and even demonstrate that Citizens United can be tamed. Just take out your pen and sign an executive order compelling federal contractors to disclose their political spending. In one stroke you can put an end to a blatant practice of political bribery that would be one small step for you and one giant leap for democracy.

It’s an open-and-shut case. In fewer than five minutes, you could face the cameras and announce your decision:

My fellow Americans. I have today signed an executive order requiring any company with a federal contract to disclose how much they spend on politicians and lobbyists, and who is receiving their money.

There are several reasons for this.

First, federal contracting is big business. In 2013 alone, the United States government spent about $460 billion dollars on contracting, with $177 billion of that going to just 25 companies. Since the year 2000, the top 10 contractors have raked in $1.5 trillion in federal contracts.
