I seem to remember such predictions, though obviously they are lost in the noise of the reverse situation that actually happened. But Does anyone have links to any notable predictions/analysis/commentary on Gore winning the electoral college but losing the popular vote?
Google has a Tools tab with options that allows to restrict results up to whatever date (up to a point, and this was in Google's early days, but it works pretty well then nonetheless). If you set it up to e.g. Oct 31 2000, and google >Bush Gore "popular vote"<, and weed out the numerous false positives, a few interesting links show up. For instance:
Some very occasional (and rather contrarian insofar as I've snooped around) commentary analyzing how Gore actually has more popular support.
You might get better insights by refining the date range somewhat. But from the looks of it, it's a clearcut no. The prediction that was usually being put forward held that Bush would win the popular vote and Gore the electoral vote, rather than the other way around.
