I disagree.

The issue is there's about 1000 fires burning all with somewhat critical importance.

But further, the left and the politicians ostensibly representing the left simply are not aligned (at least in the US). It's a rock and a hard place. Generally the politicians positions are better than the right, but far less than what the left actually wants. So they rely heavily on "what are you going to do, let the other guys win?".

Meanwhile, the right has adopted nearly the opposite position. On most positions when the base says "jump" they say "how high?".

A big reason for that is money in politics. What the rightwing base wants is generally pretty compatible with monied interests. It's no skin off the nose of a rightwing politician if they want to ban books, that doesn't ultimately harm Disney's bottom dollar.

For the left, what they want in almost all ways will negatively impact monied interested. Better regulations makes rich polluters mad. Nationalized healthcare makes every business (except maybe small businesses) mad.

That's why "left" politicians tend to only support initiatives which effectively do nothing like recognizing a MLK or saying it's ok to be gay. And even then, they are happy to ditch those positions to win more rightwing base support because, shocker, that rightwing base is likely to care less about their inaction on climate change.

You are right, though, news is a big problem. And that's because mainstream media is corporate captured. That's why left policy positions no matter the channel are always framed in the absolute worst way possible. For example, whenever nationalized healthcare comes up I can guarantee you the framing will be "How will you pay for this very expensive program that will eliminate choice and cost a lot of money which might make everyone sad and probably will bankrupt everyone?"
