The 2012 presidential election looks like it could well be another squeaker, and if it is, a number of possible outcomes could produce national hand-wringing, finger-pointing, complaints of unfairness and anger, further dividing Americans and undermining confidence in our political system. A dozen years ago, Democrat Al Gore drew 540,000 votes more than Republican George W. Bush but lost the presidency when Bush carried Florida and won 271 electoral votes. There is no reason that couldn’t happen again, with President Barack Obama winning a narrow popular vote victory and losing in the Electoral College. Most of the same states are in play as were in 2000, and any close popular vote outcome raises the possibility of a split decision, especially because Obama is likely to “waste” large numbers of votes in carrying a handful of populous states. In 2000, six states delivered a plurality of at least 500,000 votes to one of the major party nominees. Five of those states — New York, California, Massachusetts, Illinois and New Jersey — went for Gore, while only one, Texas, went for Bush. Bush carried 30 states that year, while Gore won 20 states and the District of Columbia. Eight years later, in a relative blowout, 10 states delivered pluralities of at least 500,000 votes for one of the nominees. Obama won nine of those states (the five above plus Michigan, Maryland, Pennsylvania and Washington), while Texas gave Sen. John McCain (R-Ariz.) a huge win. McCain won only 22 states that year to Obama’s 28 (plus D.C.), though the Democrat also won one of Nebraska’s electoral votes by carrying the state’s 2nd district.
