In her rounds on the Sunday shows this week Sen. Hillary Clinton (D-NY) made a point of emphasizing her support for public financing of campaigns. Though she's gone on the record supporting such a program in the past, her recent debacle with donor/wanted felon Norman Hsu has perhaps prompted a more active level of support.Here's what she had to say to Tim Russert:  Russert: You talk about the politics of change. Is this changing the way Washington does business? Clinton: Well, I’m very much in favor of public financing, which is the only way to really change a lot of the problems that we have in our campaign finance system. You know, as soon as my campaign found out what I and dozens of other campaigns did not know, that he was a fugitive from justice, we took action. And out of an abundance of caution, we did return any contribution that we could in any way, no matter how indirect, link to him. And I believe that we’ve done what we needed to do based on the information as soon as it came to our attention. But we’ve gone even further, Tim, and we’re installing even additional kinds of checks because, you know, it was something that my campaign and other campaigns going back to 2003 did not uncover in all the vetting that we do. But the real answer here is public financing, and I’m going to work very hard in my time in the Senate and then in the White House to try to get to a public financing system that we can support under the constitution, because, as you know, we’ve got some constitutional issues we have to address, because that is the answer to all of these issues that have arisen.
