We can see the entire history.

Gore ran on environmentalism. And bam he lost the election.

So what did Obama learn? Don't touch it. Not one bit. And he won.

Hillary said maybe now is the time, she said she'd have a map room. She declared war on climate change. And bam she lost the election.

So what did Biden learn? Don't touch it. Don't say one word. And he won. But Biden did green energy anyway. And what did polls say? That he was going to lose the election.

So what did Kamala learn? There is no thanks for it. Don't run on it. It doesn't get anything.

And what won the election? "It's the economy, stupid". No one is running on environmentalism for a long time.

The best we can hope for is that Dems win without running on it, and do it anyway just like Biden did.
