Should We Scrap Democracy Because of Campaign Contributions?

Do campaign contributions tarnish the election system so much that we should have the person appointed instead of elected? Are they such a great danger that in order to get rid of them, we should also get rid of democracy?

Utah State Sen. Todd Weiler is actually suggesting only that we consider that just one office, the attorney general's office, be appointed instead of elected. But, I can't help wonder if he is worried about the attorney general's office, why not all others?

"The discussion is: As an elected official in a statewide race, we're asking these candidates to run around and ask people for political donations," Weiler is quoted as saying in the Salt Lake Tribune. "If someone was appointed, we'd take that entirely out of the process."

Of a truth, being beholden to campaign contributors is a terrible weakness in our democratic process.
