Why should they work harder? Every four years they drum up votes by saying they're not as bad as the Other Guy, and about half the time it works. A large portion, maybe even a majority, of their voters come out of the woodwork around election time to call anyone dissatisfied with the Democratic party a Russian troll or worse, then disappear for the next four years until the next Other Guy needs to be defeated.

The system we have only has one way for the public to express their opinions of politicians: their vote. A vote for a politician, regardless if it's just a vote against the Other Guy, is taken as approval of that politician and their party. Now we're stuck between a rock and a hard place of our own making. Fascism on the one hand, fascism delayed by a maximum of four years on the other.
