As American elections become even more outrageously expensive, the advocacy group Public Citizen argues voters deserve to know who is making a financial play for influence in Washington. The think tank is asking President Obama to sign an executive order requiring all federal contractors to disclose their contributions to political candidates and campaigns. Such an order would mean more transparency about how much money politicians get from companies in competition for lucrative government contracts -- a competition that may be decided by the very politicians those companies donate to.
