Look, all these third parties, the Greens, Labor, the Libertarians, the Socialist Workers Party, the Sunshine and Puppydog Party, and god knows what else, are non-entities. Most of these “parties” are pretty much one guy in a basement with a typewriter and a xerox machine and a webpage. It’s what they do instead of watch sports on TV. There might be more libertarians, but they aren’t ever going to be a viable party, because most capital L Libertarians are cranks for whom fine points of dogma are more important than creating a movement.
The Democratic Party isn’t going anywhere. If the Democratic party implodes there won’t be a “coalition” of third parties forming an alternative, because all those third parties put together won’t make up 1% of the voters.
An imploded, absolutely destroyed and discredited Democratic party would still be more than 20% of the voters, just by inertia. It would be taken over and reborn as a new party with the same name.
Look at the Republican party. How much resemblance does today’s southern, religious convervative pro-business party have with Lincoln’s northern liberal antislavery party? Heck, how much does today’s southern conservative Republican party resemble the northern liberal Republican party of the 1950s?
If we ever do have a third party destroy one of the major parties it is much more likely to be a new creation like the Reform Party rather than a growth in popularity of one of these basement parties.
And why is that? Because anyone who doesn’t agree with the platform of either major party who has any political talent or ambition or desire to actually govern will never ever ever in a million years join one of these fringe parties. They’ll join one of the major parties that they disagree with least and be a “maverick”. There are plenty of people in office who routinely vote against their party. Anyone who actually wants to govern, who wants to hold office, who wants to win elections, will join a major party and try to change the major party to suit them, rather than join a minor party they agree with 100%.
And let’s face it, a reasonable person isn’t going to find one of those hypothetical minor parties that they agree with 100%, because these minor parties have decidedly minority platforms. Reasonable people join a major party, cranks form a minor party. The trouble with joining the Libertarian party is that you’ll be surrounded by Libertarian cranks. The trouble with joining the Socialist Workers Party is that you’ll be surrounded by Socialist cranks. If you want to find reasonable libertarians or socialists you won’t find them in the Libertarian party or the Socialist party.
Sure it’s circular…no reasonable people want to join a crank party, so the crank parties are full of cranks rather than reasonable people, which means that reasonable people don’t want to join them. Positive feedback loop.
