Regardless of policy, which I won't get into here, we have to acknowledge that treating adults like children isn't a rock-solid battle strategy.
This isn't some conspiracy by "a foreign power" it's well documented history
But reality: Bernie was really popular with the 18-36 demographic. But they don't turnout to vote in the general election, let alone a primary. So here we are. Old people get their way because they show up.
And I'm not saying Bernie didn't energize voters: just that it's a really high bar to energize that to a point of participation.
That was the one I paid close attention to. If 2016 was anything like it (and I'm sure it was, considering this year's convention tactics were used all the way back in the 1940s to force Truman on us), I have no doubt that this is the DNC's modus operandi. The true steal of the last 3 elections were establishment Democrats' theft of the liberal and leftist vote. And in 2 out of 3 of those cases, they paid in the general.
They never listen and are just encased in their chrysalis where everyone’s a joke to them if you arent automatically about the party lines
