Also only one state in 2012 was carried by plurality: Florida.
In 2008, Montana, Missouri, Indiana, and North Carolina were decided by pluralities.
In 2004, Wisconsin, New Mexico, and Iowa were decided by pluralities.
In 2000, Oregon (this seems really weird in 2017, huh?), New Mexico, Minnesota, Iowa, Wisconsin, Florida, New Hampshire, and Maine were decided by pluralities.
It appears as though elections without an incumbent running have far more plurality victories (2000, 2008, 2016) than those with an incumbent running (2004, 2012).
