No it is true, nominating Garland to begin with was a major capitulation to Republicans. He was basically a moderate Republican that made the base not care about the nomination.

And Democrats could of and should have shut down the government over what McConnell did but did what they always do. Perform a right wing ratchet where they simple stop the country from becoming right wing but never push it left. Then when a Rep comes into office the push the country right once again which is exactly what happened.
