This is the challenge that the Democrats have; the Republicans have a policy that appeals to a significant enough percentage of the population, while the Democrats have to try and appeal to "everyone else". A two-party system is not a democracy, it's a compromise, and only a political revolution will fix it.

Of course, that's also what the Republicans / Heritage Foundation are aiming for, if they have their way they will do away with democracy. Which isn't exactly what I was thinking of.
