President Joe Biden capped off his half-century political career on Wednesday evening with a final Oval Office speech, hoping to seal a legacy that has been overshadowed by Democrats' failure to stop Donald Trump from returning to the White House. In his farewell address, Biden warned of the dangers of the concentration of power and wealth, highlighting the emergence of an "oligarchy" and a "tech-industrial complex." How will Biden’s legacy be perceived in years to come? We spoke with Nancy Kassop, Distinguished Professor of Political Science Professor at SUNY New Paltz State University in New York.
