If John Kerry won the presidency in 2004 by just flipping Ohio while losing the popular vote to Dubya, would a serious movement to abolish or reform the Electoral College have emerged? After picking the "wrong guy" twice in a row while both parties got screwed, I think there may have been some support from Republicans as well.
If only Ohio is flipped from actual 2004 results, Kerry wins 272-266 while losing the popular vote by more than Bush did in 2000.
Both parties would support the notion further, but I don't see it happening. Another way to look at is that both parties were even and moved on. Bush himself would've never made a big deal about losing re-election no matter what the results were.
