Well, to be fair to the US, the popular vote gap in 2000 and the district lines here causing MP coverage to be so wack (gerrymandering?) are quite different in nature. The electoral college is written into the US Constitution, making it next to impossible very difficult to change, whereas UK election law is...er...interesting but less difficult to manoeuvre.

There was a lot of talk at the time (and has been at each presidential election since) about the dubious relevance of the electoral college system, but as noted, it's too darn hard to get rid of it.
