According to The Independent, some right-wing commentators even went as far as questioning Sanders' intellect.
However, others criticised her for not offering a clear enough rebuttal to Biden's speech.
Meanwhile, left-leaning commentators questioned the validity of her claims about the left-wing culture war, accusing her of fear-mongering.
Sanders' response to Biden's speech largely focused on issues of individual freedom and government overreach.
She claimed that Americans are "under attack" in a left-wing culture war that they did not start or want to fight.
She also criticised the collusion between big government and Big Tech, claiming it was stripping away Americans' right to free speech.
Overall, Sanders' response to Biden's speech received mixed reviews from commentators across the political spectrum.
While some praised her for championing issues of individual freedom, others criticised her for relying too heavily on culture war issues and not offering a substantive rebuttal to Biden's speech.
