U.S. President Donald Trump has framed the first general election debate as a test for his opponent, former Vice President Joe Biden.

Yet he has simultaneously set the bar so low for so long that many of his supporters — having watched unflattering, often manipulated clips of Biden in Trump campaign advertisements or on Fox News — are now expecting the president to mop the floor with an incoherent opponent in something resembling a WWE match.

Democrats — and even some Republicans — believe that is not likely to happen.
