Dukakis is a good addition to the list. He's why I voted for Bush I in '88.
As to the "But Romney's winning" bit, no he's not. He has never been in the lead. The popular vote is irrelevant, though that too is certainly trending Obama at the moment, after no bounce for Romney from either the Ryan VP nod or his own party's convention. At no time this year, in any poll I have seen, has Romney been forecasted to win the electoral vote. Nate Silver's work at 538.com currently shows Obama with a 317-221 lead - and increasing.
Given that the GOP is significantly reducing ad spending in Michigan and Ohio (and early indications suggest PA as well), given that the Virginia GOP is trying desperately to keep Constitution Party candidate Virgil Goode off the ballot (despite the fact that he had more than double the number of signatures needed to be on the ballot) because his presence almost guarantees the state for Obama, things are quickly going from bad to worse for Mitt.
I've rarely in my lifetime seen a major party candidate that was neither able to appeal to the base, nor sway the swing vote. Normally a candidate does at least one or the other. Romney does neither. He basically has the "he's not Obama" vote, and history pretty consistently shows, that's not enough. It's why Kerry didn't win in 2004.
