That eliminates TV campaign ads. (I sure don't miss the ads for the Virginia campaigns.)
And see, that's another thing - if you don't "campaign" - you can still go on talk shows and news and radio shows. Trump in 2016 managed to stir up so much news, he got hundreds of hours of coverage without SPENDING A DIME.
If MONEY could be erased from the political world - we could end most of the corruption.
You can't corrupt someone without at least the PROMISE of money or affluence. Well, that, or threats.
