Personally, I judge people in office by what they do rather than what they say. I am pleasantly surprised by Mr. Biden's effectiveness given the polarization in Congress and the nation.
From the responses in this thread, my sample of "leftists" must be "utopian" leftists. They view Mr. Biden more as an opportunity lost than an opportunity gained (or a disaster avoided).
President Obama used to tell us not to let the perfect be the enemy of the good. Biden is not perfect and never claimed to be. Like Obama, he wants things like universal health care, free education, equal rights and treatment for all, humane treatment for refugees, rich people paying their fair share of taxes, etc.--everything that utopian leftists want. Biden and Obama just have realistic expectations of what can be achieved, given the reality of how the government works in the US. Despite their similar attitudes and approaches to governing, a lot of utopian leftists give Obama a pass where they cut no slack for Biden.
