You can't get rid of ads. But ads should be transparent and it should be visible to all that X paid for an ad, sent it to Y group and said Z. That would prevent politicians from, for example, advertising to people on one side of an issue that he is on their side, and to people on the other side of an issue that he is on their side, knowing that neither group will see the other ad. Then they could keep people from doing new last-minute ads right before an election so they can't sneak in whoppers before the honest press can catch them.
