If you want a third party, then vote for them for state government or something local. Green is not a serious party because they have no local elected politicians and cannot win the presidency. We’ve already been through this when Ross Perot successfully knocked out Bush in 92, Dole in 96, and Nader knocked out Gore in 2000. You can vote for whoever you want but when you see who’s behind her campaign, it’s clear she’s being promoted in order to hurt Harris.
