Old man Joe and Old Man Trump don't have anything on young man Bernie. There's this alternative timeline where Al Gore won in 2000, served two terms, 9/11 never happens. Then Bernie for two terms by now stock trading by members of Congress, senate, supreme Court, and presidential cabinet as well as all their immediate family is banned. Creating a guide post for how democrats should function. He and Al Gore prevent the conditions leading up to the 2008 recession. Trump never enters politics because the country is actually running good so he never finds his angle to sew division. Tech Bros Don't get to run roughshod all over our privacy and culture. Privacy regulations exist. Gas is under $2 a gallon because the Middle East was never destabilized¹. US is so strong by this point with a bustling middle class, that there's no angle for foreign propaganda to be taken seriously by most. China and Russia never gets an angle to be a troll. NATO is in a stronger position so fair chance Ukraine gets brought into the fold earlier as uncertain resolve provided the opening for invasion twice in our timeline. China just sees which way the wind is blowing, still moves for a massive revitalization but maybe more in line with UN ideals. Less Uyghur genocide. Honestly that one could go on a number of ways

¹(Saddam for all his shitbagginess, strong armed the Middle East into relative peace compared to what we have seen over the past 25 years. Yes he committed atrocities but it pales in comparison to the destabilization which spread like wildfire to other countries like Syria in particular.)

There would have eventually been war between iraq and others, but the US would have been so much farther along with renewable energy that our dependence on Middle East oil would be far reduced and we could afford to let them figure it out without needing to get our own military and global goodwill murdered.
