You're right. What's been done so far won't fully solve the problem. Better undermine support for people trying to get what can be done, done, and then doom all over the Internet.

The libs are the ones undermining the progress. It ought to be self evident by now that radical measures need to be taken, and that the markets will not solve the climate crisis, the kind of regulation we need would kill entire sectors of the economy. Even when it comes to moderate improvements, Democrats are obstructed by both the minority opposition and members of their own party (as libs are always quick to remind me).

The Democrats will never be able to do what needs to get done. So you undermine the chance for meaningful change when you tell people, "don't worry, Biden is on it, just vote and everything will be fine".

Nah, even in areas with ranked choice voting, third parties are jokes. Don't get me wrong, I'm in favor of reforms designed to allow them a more reasonable and equal access to the political levers of power, but the two most significant third parties are the Greens and Libertarians. Neither one is a political force, and not just because of first past the post voting. Niche, ideologically focused parties will always underperform wide coalitions within democracies.

Which areas? Areas in the US? Yeah, hundreds of years of entrenched power at the local, State, and federal level will do that. Would take time and likely ranked choice at the federal level to change.
