Maybe if you only see the political ads of a single party. It would still be better because you would know of even a single stance of one party.
Last election, I can’t remember a single actual stance taken by any party based on political ads. They were all attack ads. Without discussion you couldn’t separate the resonable accusations from the trash anyway.
Basing your politocal opinions purely on ads is a terrible stance anyway, and the party best at fearmongering will win there. There aren’t any restrictions on ads that can fix people forming opinions only on ads anyway, we’d need to encourage public political debates and discourse instead.
