USA Today writes today in support of public financing for presidential campaigns, arguing that the escalating cost of campaigning has overwhelmed the current system, but created an opportunity to pursue a Clean Elections-style system of public financing like those in Maine, Arizona, Connecticut and elsewhere.  The editorial points to success stories like Governor Janet Napolitano's prescription drug bill in Arizona -- the success of which she credits in part to the Clean Elections system for allowing her to run for office without having to solicit contributions from pharmaceutical interests and others who would have opposed the bill. With, as the article notes, presidential candidates forced to eschew public financing to run viable campaigns, and with big donors increasingly dominant in the fundraising wars, the seven Clean Elections state and two municipalities provide a good example of what Congress should pursue both for its own elections, and for presidential elections.
