Throughout his career, Democratic presidential nominee Joe Biden has suffered from a series of self-inflicted flubs. Unlike President Donald Trump, Biden has been held accountable by the media and the public for his gaffes. So far, none of President Trump’s slips of the tongue have derailed him.

Far from being the “Teflon president” like Ronald Reagan on whom mistakes did not seem to stick, Biden faces a media that continually looks for gaffes and attempts to establish a pattern. At the same time his political opponents use his verbal mishaps against him. President Trump has already questioned Biden’s fitness for the job by implying that his gaffes demonstrate his intellectual incapacity to lead the country.
