I want as much radical change as we can get in several directions. There is a lot clearly wrong that can be fixed [especially a huge variety of economic, regulatory and political organizational issues. ideally some constitutional amendments…] Bernie Sanders and Elizabeth Warren seem like the most aggressive reformers (especially Bernie), but I haven’t looked into the details of all of their proposals (where there are details), so I can’t say they where are right and where they might be wrong. You can’t expect a political platform to ever be quite right. You just have the choose the one that will bring us in the best direction. (If their policies are economically ruinous that would not be the case, but I’d caution to anyone concerned here that few or no mainstream economic policy ideas are academically sound…)
In general I’ve not agreed with the electability and mass-appeal argument for Joe Biden. But combined with some of his proposals in the past week for serious political reform, I think there is an argument for him best being able to improve the basic functioning of our country, which may make us better off in the end. The number one issue for our long-term success is our total dysfunction. America is angrily and unproductively divided. The political system is partisan and openly antagonistic. We increasingly can’t agree even on basic facts.
We could use a president who can help “heal” the nation. And it may be more productive to be able to make some of the many important issues bipartisan, even if it delays the most progressive reforms. And the process is probably more sustainable.
I haven’t watched any of the debates and probably won’t this one, so the above is more of a philosophical perspective in which you can insert your ideas of about the political candidates and their platforms.
