The Bush era has been the worst disaster for the right wing this century in both the US and potentially globally. He was a warmonger, an economic vandal and an unprincipled man at the helm of a state that flubbed any chance at setting up for meaningful long term success in favour of the patriot act and slaughtering goat herders in the middle east. Under his eye the Republicans exiled the right from cultural relevance for around a decade. The party around him were cut from the same cloth.
There is a reason the modern Republican party went with Trump rather than another person who looked like Bush. The entire Trump story has been the Republicans - without too much recrimination - attempting to purge the remains of the Bush era because they were a gross embarrassment whos legacy has been little short of a disaster. If the US Democrats had undertaken the same purge instead of embracing the leadership of the same era then they wouldn't have tried to run Biden then Kamala.
