Well, I've been watching too much West Wing again, and reading about how much time Congress spends raising money, and not legislating.
The money is needed for TV ads. However, if everyone with Tivo (or any digital video recorder) stops watching ads, well, there's no point in raising all that money. It'll be hard to replace TV ads for product placement, for politicians.
There'd be some unintended consequence, but I feel it's now the patriotic duty of us all to skip political commercials.
(re West Wing, looks like Josh and Donna are going to work out.)
