I had an idea, but I don't know who to pitch it to or if it's good or bad or has already been done.

It's unfortunate, but our political process is coin operated--this is even more clear since we decided corporations were people and moneys political speech. Someone, perhaps someone here, needs to make an app that lets you see a company's political positions on the fly. If they have physical products, scanning the barcodes could let you know what the company lobbies for and who they support. Said app could do other things, like informing the company how their political meddling influenced your purchase (for or against) and/or recommending an alternative product or service from a company/provider with monetary speech you find more palatable.
