Electing a legislator is not electing a dictator. The system was designed to give people with good ideas a chance to lead, not just professional politicians. Your attitude is borderline elitist and leads to the "ok it's my turn now" phenominon that's made the Democrats so ineffective in the last couple of decades. The only time anyone's gotten excited for them in recent memory was Obama, who had been a politician for a whole 4 years before becoming president.
