You could say that with the way Democratic primaries went down, however,its not surprising that Trump lost, there are many that would have previously voted third party or for Trump as a protest vote (due to the Democratic party not serving their interests) and they are now sick of him whether it be covid, no further economic stimulus for the people and realising that the swamp is just further highlighted not drained.
Both parties are toxic and have a corporatist agenda and much of what Trump said during 2016 election was untrue, he packed his team full of people that were from big busness like Goldman Sach’s that were part of the so called swamp. So when people talk of him favourably they don’t look into what he actually stands for. Though at least he added some humour while he screwed over the citizens which is better than nothing i suppose. Though to dismiss the differences between the two would be criminal too its an improvement with Biden but mostly its the decorum that they want restored that’s why you see Republicans supporting Biden.
