What That Campaign Sign Really Says

Campaign signs are everywhere this time of year -- in neighbors' yards, on the drive to work and maybe even in the windows of local businesses.

Do they work? Or are campaign signs a waste of ink and paper? In campaigns for president or U.S. Senate, signs and bumper stickers won't make much of a difference.

But research by political scientists Cindy Kam and Elizabeth Zechmeister  suggests that signs might positively influence voters in races where little to no information exists on the candidates themselves -- like judges. So how does it work? And do certain kinds of signs work better than others?
