Not the presidency. That's pie in the sky.
But the Green Party wins some solid statewide races. And it's more than just environmental issues, as important as they are. It's a variety of issues, usually on the more liberal side of the spectrum. The party sometimes styles itself as little d democracy. In practical terms, elected officials would often caucus with the Democrats.
All the same, some thunder on the left would give the Democrats a real ride for their money! Plus a chance to position themselves as the more moderate alternative.
How do you see this playing out?
