But in that quote they're still trying for progress...
Which is my point. We'd get more votes if we ran people that tried and failed than running people who say they can accomplish things during a campaign, then call voters uneducated in our political process when we complain they haven't even tried yet.
All we need to do is make realistic promises in what a candidate can do, and try for things even though we don't think it'll work.
Voters hate not trying, but we understand failure.
