Why are critics so concerned about voters getting most of their information about candidates from television?

Because most people watch more television than the do read the paper. so... if you put an ad. on television enough times, it will get stuck in someones' head and they will constintly talk about it and talk about it. But if it was put in a newspaper, most people dont really read the paper. If anything the skim through it. Therefore, people will look past it, and not even know about the information.
