Perhaps. But I have seen parties be taken over by their membership voting for candidates, and implode. Because the people who vote for candidates aren't the wider public, and they're also not the people who actually get voted for. They're nuts generally.

The DNC is for corporate kowtowing, e.g., genteel corruption.

If one is to use the word "fascism", it would behoove one to understand what the word means: https://www.merriam-webster.com/dictionary/fascism

Then with that definition (or similar), iterate through its qualities and evaluate examples of each party that may or may not exhibit such behavior and beliefs.

I'd be interested to hear your evaluation of such an endeavor.
