During 8 years of Obama and 4 years of Biden, none of this was different or better. Perhaps this isn't a partisan political issue.

From 2014 until it was, in effect, obliterated by DOGE actions this year there was the "United States Digital Service", a crack team of programmers, a sort of skunkworks who worked to improve U.S. government websites of departments that wanted the help. So it seems to be partisan to want good websites, but there are countless people involved in politics with many agendas.
