I'm convinced that unless you have some public financing of elections, you are never going to remove the power of wealthy interests over elected officials.
At least I make decisions based on what I think is right, not who my friends might be.
My belief is the majority of people in politics are just interested in pursuing this career in politics, and doing what's necessary to get themselves re-elected. And if that happens to coincide with the public good, great. But if it doesn't, the public good loses out.
You have the biggest impact on controlling, on affecting local lives as mayor. It's so much more important than being a state legislator.
I'm not going to rule out running for a second term. But, I think you have to be psychologically prepared to walk away from the job after four years. It's the only way that you cannot be influenced by those special interests.
