I usually stay well clear of politics (gawd knows I get enough of it shoved down my throat at work) but I'll have a go at answering your post Andy regarding how a situation like this can happen - in the good old fashioned black and white days when much of dear old Blighty was festooned with half timbered houses with no toilets and courageous, thrill seeking types in Witchfinder General outfits set sail for far away places in galleons made from rather large oak trees, some of my ancestors on my dad's side of the family were amongst the very first settlers in 'the new world', so consequently I have a lot, and I mean a
lot of relatives spread right across the US. In recent years my brother, my two sisters I have been keeping in touch with some of them and I'd say that politically and in general outlook they are divided roughly 50 / 50 between democrats and republicans. They are from all walks of life - blue collar, white collar, agricultural, industrial, managerial, artsy, liberal, conservative, very left wing, very right wing, gun toting, gun fearing, god fearing, religious sceptics and in a few cases a strange mixture of all of these things. One thing above all else is clear when talking to them, both 'sides' feel as though the 'other side' aren't listening to them,
this is why the nation is so divided and it goes way back before Trump appeared, it's really very deep rooted in so many of them. Trump is the straw which broke the camel's back. There was a huge swell of support for the tangerine gimp from people who would never normally give him the time of day, partly as a protest vote, and partly because they thought Obama just hadn't been listening to their concerns and the thought of another Clinton in the White House filled them with utter dread. There were a myriad of other reasons of course, and it isn't necessarily all black and white within that 50 / 50 divide because even some of my more liberal minded, highly educated, successful and motivated cousins over there couldn't put their crosses in the box marked democrat come voting time, because they didn't want more of the same and could see that great swathes of the lower educated and motivated population felt that way too.
Rightly or wrongly, this is where we are and it is not going to dissolve or go away when Trump is dragged kicking and screaming from the oval office. I sincerely hope that Biden picks up on this and somehow manages to calm the waters, or at least make a start, let's hope he can get to a place where there is some balance in US politics again. It won't be easy for him and I doubt he'll be able to do it in one or two terms, but if he can make a good start it will pave the way forward for the next president after his time in office, by which time Trump will be a distant and very bizarre memory.
