Concept the first: When you hover over a Senator or Representative’s name (or an MP’s name in England) a little pop-up box appears (like the spelling corrections one) which identifies major companies that have donated to that individual (or PACs that support that individual). Also major individual donors. Also a little percentage of “small donations” vs “large donations” for their last re-election campaign.
Concept the second: Further extension such that if you visit one of their websites a scrolling banner with the branding for every major company that donated to / supports them trundles across the bottom of the page.
Anyone with better coding skills than me want to make it happen?
