I do not believe that today’s Republican party has the right to survive. But this has nothing to do with Sanders’ call for political revolution.
For one thing, Sanders called for political revolution before the Republicans started their coup (and it is a coup, not a revolution). But even if someone were to argue that Sanders “political revolution” is a response to trumpian one – my opposition to revolutions also applies to counter-revolutions.
We do not need a revolution, we do not need to throw away the institutions this country built for over 200 years. We need to defend these institutions, improve them and use them for further progress. In other words, we need an evolution.
And if you look into the matter, you may be surprised how quickly things tend to evolve under the right conditions.
