Man, none of that will work. Since Reagan the Dems have only won because the R's crashed the economy/started wars. We are and have been the frustration vote. Ds comes in and gets things back on track again and then we are right back to bringing in Rs to fuck it up.
The problem with trying to unite the Ds is the olds and religious. Neither like progress. Full stop. You can talk about how Trump fucked you over, isn't the guy you voted for, or has changed. As long as you are also trying to sell trans rights and brown people they will never be on board. And even if you finally do get a generation of them to accept one social issue the next generation of them will be right behind them to put their foot down on the next one. It continues on decade after decade. The Rs tapped into that vein and it's a larger voting block than progressives who are much younger.
Young people don't see the value in voting. D politicians know that. So what we get is Ds trying to placate to olds by moving right in their ideology and policy which is even more of a turnoff for young progressives and marginalized parties, so even less turn out to the polls. That is how we got Trump in the first place. Now this last cycle Harris may have had a chance but too many saw her as "more Joe Biden", and the Rs correctly sold it that way. The unwashed don't know VPs don't make policy. They also don't understand the chain reaction from Pandemic handling. All they know is when the inflation was at its worst Biden/Harris were in the office.
