No one has to justify a third party running against the damn Democratic Party. That party and the other rotten party have taken control of this system and made it so no other parties can really challenge them. They are corrupt and rig things internally whenever the interests of those running their party and their donors are threatened, and the Democrats are internally undemocratic. If a Democrat runs and loses votes to the Green Party, those voters didn’t owe the Democrats anything, and they don’t have to justify voting for the Green Party. If a Democrat in 2000 or 2016 lost votes to the Green Party (more times than not, their horribleness or mediocrity simple resulted in people not bothering to vote at all), that means that they should have offered those voters more if they wanted their vote. In other words, earn the damn votes. They didn’t, and so they voted for other candidates. The Democrats should, instead of waiving their corrupt plutocrat fingers at others, work to make their party less corrupt, work to create ideological coherence in their party, work to get more people to vote (by giving them a reason to vote), and they should open up the political system. Don’t the neoliberals always talk about the magic of competition? How does that not transfer to politics? Open up the political system to competition from other parties, not just on the left. Let the Greens and Libertarians take part in presidential debates and take away the control of those debates from these two rotten parties. I would love for the Greens and the Democrats to compete for the chance to take on right wing parties, and would like to not be stuck with that corrupt, out of touch party, since it offers no solutions to our largest problems and has no policy or ideological coherence. One reason we are stuck with sub mediocre thinkers and politicians is because of the well-established Democratic networks and affiliated think tanks. Other parties would blow that to bits. I would welcome that.
