I read lots of screaming on here about the Left, and I get it. The Left is VERY online and punches way way above its weight in communication capability. You'd think they would be the bloc to make or break the Democrats.
Here's the thing: politically they are irrelevant, as the following evidence will support. Certainly not enough to warrant the hand wringing on this board. There just aren't that many of them, at least those who vote.
Biden has been crushing the primaries up until now. If the Left was such a large presence, surely they could drag themselves to the polls and vote for Marianne Williamson at a greater clip than the 2% she has been getting? Nicely matches the 2% Tulsi Gabbard was drawing back in 2020. Now, Bernie had a good showing in the primaries in 2020 as a Leftist, but he at least has some responsibility and mainstream cred after being in the Senate like 20 years. He heads the Senate Finance Committee, FFS. That takes the edge off.
Next comes the Border Bill, which - let's be honest - was a fucking awful conservative's wet dream of a bill. It had the potential to be a total wedge issue for the entire left-of-center crowd. But most Democrats would have happily voted for it and Biden was going to sign it. Why? Because they know damn well that the number of independents/moderates they could have courted vastly outnumbered the amount of Leftists they would have pissed off. It was a total poison pill but worth it electorally, because the Left is loud but otherwise inconsequential. Now it's the Republicans, in their extreme idiocy, who decided to not only torpedo their own Democrat subversion efforts, but to OWN it. Fucking clowns. There are Republican strategists tearing their hair out right now.
AOC is basically a team player at this point. Ditto Bernie and Warren. Sadly, they have both stopped talking about single payer healthcare, but there is a simple explanation.
