Pop-ups

You know all those pop-ups that try to get you to buy something or visit some website by using various attention-getting ploys, like shooting the ducks? What's with the ones now that show a picture of the president and say "Should he be reelected?" (sorry, no link available [no one links to a pop-up -- pub]). Half the country doesn't even vote, so why on earth would you expect a pop-up to generate interest on that question?
