They're probably on the list because they supported inane 'gun control' laws and background checks that they should have researched before spending millions of dollars backing them! You would think that the billionaires would be a little bit wiser checking where their money is going and being wasted. If I had their money I sure as hell wouldn't give it to the idiots that came up with 594. If they were really that concerned with gun control they could start and fund their own movement to push some legislation that could actually make a dent in the problems that we have today in our society.
