I ran across this great photo and question on StumbleUpon recently (though, I’ve seen it before — maybe on StumbleUpon :D). Aside from being funny, that actually seems like a pretty darn good idea to me! Seriously, it would be convenient to us citizens (and much more useful than their phony TV ads, claims, and promises if we could just see who the heck was sponsoring them by looking at their clothes.
Sorry, actual source of the image unknown. (The politician, however, is a heavily sponsored Mr. John Boehner, Republican Speaker of the House.)
