So is next election cycle the one to support a third party? Or the following? Will there ever be a time when it's OK to support one other than the lesser of two evils for the rest of our lives?
Hoping that it is given to us, and doing nothing to build the political powerbase to make it happen doesn't help. These changes we want to see need us to build and maintain coalitions, not just wait for other people to do the work for us or approach it like one person can fix the issue. If there are changes you want to see in the world, start working with you friends and family to get the word out about the issue and start doing things in your shared spaces to get that to happen.
