There are several things wrong with this:
1) These aren't all Bernie's people.
2) Even if they were, did anybody see the ruckus at the Democratic Convention? Bernie can't control them.
3) The mere idea that some Democrats think that these protests at their offices are just more upset "Bernie people" and not liberals in general pissed off at Democrats not reacting to the moment just shows how out of touch some of these Democrats are with their own base. It's infuriating.
This is the jewel of the problem, I think.
People in this country are struggling, and they want actual solutions. For the left, it is increasingly being aimed to arm a message and a direction, to support actual policies, movements, and ideas, that it seems the Democrats, at least higher up, do not understand.
I would imagine most of the Democratic party is like Nancy Pelosi. When even
questioned about the failure of social policy of the last 35+ years -- particularly neoliberal Capitalism -- she doubles down on Capitalism and makes excuses, saying it's "shareholder Capitalism" as if that's some fluke. She wouldn't even concede with a Millennial who even asked her to open her horizons regarding a new approach. You know, the same generation hating Capitalism almost in full because it's become a machine to exploit, abuse, and they have nothing to show for even trying to "follow the American Dream" within it. They don't hate it because they're lazy; they hate it because it's not fucking working for most people in this society. People like Sanders and Warren have been political beacons for this for many years, but I would imagine people have become far more active as they see neoliberal Capitalism be replaced with neonational Capitalism, which is several degrees worse, offers no solutions, and makes several bullshit narratives of scapegoating that only promise things get worse.
This "old guard" really doesn't have a clue a precariat class has formed in this country, and they're not only befuddled at the "protests" aimed at them, they haven't a clue on how to handle it. They've normalized decades of increased precarity and a game that's worked for a few that most of them that they really haven't a single idea on how to reverse course, for they're only really focused on making sure the GOP doesn't pivot the ship into icebergs. But what if the ship is already insolvent and filled with water?
I mean, you can even say their inaction and passivity to even nominations the GOP is getting away with as a normalization of this problem, for they're not even preventing them from getting through the front door, in a sense.
