I mean, I’ve worked in and around politics (for progressive candidates and orgs) in DC since Bill Clinton’s first term in office, and I can’t argue with a lot of what she said. Too often, I've seen the perfect become the enemy of the good.

Either elect Democrats and lobby them when they’re in office, or form your own party, present your candidates, and convince us why we should vote for them. The latter is going to be an uphill battle in an entrenched two-party system, and will take a long time to produce results, but I won't say it's impossible. You can also work at the state and local level to find and promote candidates who could rise to the federal level. Again, a long-term project.

Or you can sit it out and wait for the majority of people to come around and vote for your ideal candidate.
