Clinton/Romney
55/42 is bigger than anybody has won since Reagan. That can't all be from driving up the vote certain places, because the Democrats are just about maxed out in some of the larger states. I gave Clinton KY since she seems to poll well there, but you could easily add - or replace with - other states.
Romney/Obama
Republicans seem to underperform in the EC these days so a nine-point Romney win would produce less of a sweep than Obama's seven-point win in '08. But he would still carry every possible swing state from '12.
