Lots of self-reflection for the Democrats, they need to work out a strategy to compete, not against a political opponent, but against a cult of personality. A man who stands for nothing becomes a mirror, reflecting back what others wish to see.
They need to focus on how to better deliver the message that their policies will be better for working and middle-class Americans, and for the love of God stop fannying around at events with millionaire celebrities. Their endorsement helps galvanise the base, but has little impact on everyday Americans.
The left too often is dragged into culture wars which heavily benefit Republicans. They need to stop trying to win the argument, they need to change the argument in order to win.
Take the trans kids in sport issue, turn it around. Are you more concerned about your daughter losing a swimming race to a trans child, or getting killed in another school shooting?
They also need to go into the Lion's den more, Harris should have done the Rogan podcast, calling him out on his previous comments about Trump. Do more interviews and town halls on Fox, I remember 2016 when Sanders, and then Buttigieg did a Fox town hall and ended with standing ovations, the Fox anchors didn't know how to respond. More of that is needed to win.
