When will the country become more united and less politically polarized and have more landslide elections that become more common?
1) A prevailing candidate—applicable to both Republicans and Democrats—who has such a winning campaign message and approach ends up carrying the U.S. Popular Vote well north of 10 percentage points (which, over the last two elections, averages about 13 million votes and even better).
2) As the trend is already moving, whites becomes less a share of the vote nationwide. In 2008, losing Republican John McCain carried 22 states. 17 of those states—combining for 101 electoral votes (subtract one from his failure to hold Nebraska #02)—were won very much in part because the whites' share of the vote from those states, multiplied by their Republican/McCain vote, was enough to immediately carry those states. The five states—combining for 73 electoral votes—which were exceptions (in ascending order of their carried percentage margins): Missouri, Montana, Georgia, Arizona, and Texas.
Right now, we're in a period in which the percentages of carried states is almost close to the 1876 to 1896 period (to cite 20 years and six election cycles just like with 1992 to 2012 and those 20 years and six election cycles). Maybe it's not quite that bad.
That was a period in which no presidential winner reached having carried 60 percent of that period's available states.
