If the premise is that voting in as many democrats as possible will save us, then I think that is naive at best. The conditions that were necessary for the advent of Trump were created at least in large part by the policies ushered in under the Clinton “new democrats” with the backing of the Democratic Leadership Council, including
Three Strikes Crime Bill
Repeal of Glass-Steagall
And if Monica Lewinsky had not happened, Social Security was next.
If the Democratic party does not swing back sharply leftward, we will see Trump for another 6 years, or someone much worse in the future.
That is why I would prefer a new party without all of the institutional baggage.
