Biden and Harris are not it if you want to push Democrats and the country left. They aren’t as far right as Trump and his buddies, but the are left of center but pretty classic Democrats. Bernie was the guy to push things left, but the Democrats rejected him. Without a good progressive candidate in place to challenge in the primary, we won’t see that push left. This election it’s Harris as the best bet for keeping Republicans from doing serious long term damage to this country.
