I am Solomon Kahn, Harvard Fellow, visualizer of who gives money to US federal politicians. Ask me where your politician raises money from, and I'll show you using my newly launched visualization. AMA!
My short bio: I'm Solomon Kahn, fellow at the Harvard University Ash Center for Democratic Governance and Innovation, former fellow at the Safra Center For Ethics. I've built a super powerful tool to explore who gives money to federal politicians, and it just launched to the public!
Ask me about where your Senators and Congresspeople raise their money from, and I will show you.
You can also play around with the visualization yourself here: http://www.explorecampaignfinance.com, and if you're interested in staying updated on the project, you can join our mailing list here, or follow along on twitter.

Edit: There's some pretty powerful functionality that isn't immediately clear to some people. Click on any of the legend items to see the companies that make up that total. Click on any company to see the individual donations. Click on any rectangle in the main chart to see subsectors. If you find something interesting, click on the 'User Submissions' link, let us know, and we'll work to get it in front of journalists. Enjoy!
