I like to engage in the sheerest of blue-sky speculation about possible interesting outcomes that could happen. This time around, the scenario I've been hearing bandied about is that Barack Obama wins the Electoral College vote, but Mitt Romney wins the popular vote.
Before Election Day, ask yourselves this: Is Mitt Romney really the kind of dude you'd want peering over your shoulder while you stand in front of your Weber wondering why the burgers are sticking to the grill again?
While Democrats will decry Santorum's views on social issues, and the Republican base will rally behind him, most truly independent voters may largely ignore his extreme conservatism on social issues, simply because they don't really care about the wedge issues.
The less from 2000 is that the idea that one can "teach the Democrats a lesson" by voting for a progressive third party or not voting at all and thereby allowing Republicans to win just doesn't seem to work.
