The people are either fools or more likely just liars saying what they think is likely to get them elected. Anyone with a lick of sense knows that the only way to get things done is to become an "insider". You do favors for others with the expectation that others do favors for you. You get "pork" for your state. You become part of the old boys network.
Any "outsider" if they actually tried something would easily get stonewalled. The only way it could possibly be accomplished is if there was an overwhelming majority of "outsiders".
