Unpopular opinion, but I think we're giving a little too much credit to the average voter. There are a lot of low-information voters out there who don't pour through the booklets and published rebuttals and rebuttals to the rebuttals. Media saturation works. It doesn't always work, and you can always go back and find exceptions, even some very high profile ones, but if it didn't work in general, we wouldn't see so much money pouring into political advertisements. There's a reason we track and measure campaigns by counting dollars spent.
