They exist merely to help an incumbent conservative president win by siphoning votes away from disgruntled progressives. They come out of the dark at election time, then disappear after the election, like demented cicadas.

They are a fake party that comes out every four years (after primary season, when they could have become an actual viable candidate in our broken two-party system), to be a spoiler candidate that siphons votes from the Democratic party.

Every time.

Then they disappear for four years, and re-appear again at the same time during the next presidential election cycle and do it all again. They are not a serious party. If they were, they would have actual candidates running at state and local levels. They would participate in the primary process and/or campaign to switch away from First Past the Post system.

But they do none of that.
