Democrats will do better playing by the rules than denouncing the rules

When you lose a game, particularly a game you had good reason to expect you’d win, do you try to figure out how to play better? Or is your first reaction to demand changes in the rules?

In the case of the Democratic Party, it’s the latter. Perhaps that comes naturally to a party that takes some pride in having advocated changes in rules that everyone today sees as unfair (even those, like racial segregation laws, that they enacted themselves). But sometimes it’s wiser to change the way you play than to denounce long-established rules.
