When will this hideous polarization end?

It's complicated. If Democrats can win Senate elections in North Dakota and Republicans can get reelected big in New Jersey, big wins are possible.

Even in the case of massive landslides, a good chunk of the population was against the winner.

Ronald Reagan won 49 states and 37,577,352 (40.6% of the population) supported the other guy.

In FDR's best showing, 36.5% of the populace preferred an obscure small-state Governor.

Some things may be worse now, as politics has become more nationalized, so liberals have less Republicans to support and conservatives have less Democrats to support. But as long as you have people who genuinely believe that their policies will help more people achieve their potential then the other side's policies, you'll have polarization.

Two more points.

For political junkies, a period when races are close would be more interesting than a period in which races.

The odds of a landslide in the near future are limited.

Democrats have been in the White House too long for Hillary to reach her full electoral potential. She could do well, but her odds in states like West Virginia, Missouri, Arkansas and Georgia would be higher with an unpopular Republican in the White House.

Hillary also seems to be too strong a Democratic candidate for Republicans to have a cakewalk no matter what the national mood. It's not going to be 1920, where a decent Democrat loses by 26 points.
