Should we forgo regulation of campaign finance generally and instead solely regulate lobbyists?

It seems the more I learn, the more lobbyists seem to have an unfair advantage. Is it time, therefore, that we take the focus off of politicians and put it on the lobbyists, as they are the people who clearly know where the money is coming from, and what they want to do with it?

If we can’t give money to candidates, aren’t we supporting a truly democratic system?
