"Hey you know how there is an unbelievably close race between a centrist who wants to maintain the status quo but may occssionally bend to public pressure and an outright madman who want burn democracy to the ground while lining his own pockets and rolling back social progress to the 1850s? You should totally protest vote for a party that doesn't have its shit together enough to even get on the ballot everywhere and has no chance at all of winning. That will show them how you really feel!"
I cannot imagine why main stream American politics doesn't take leftists seriously.
Grow up.
