Nobody asked me, but ... it will be interesting to see how many counties across the nation end up as "landslide counties" in November's election. Authors of "The Big Sort," an important book on demographics and politics, pointed out a few years ago that the country had become more politically segregated than ever: Americans now generally live among the like-minded — Republicans among Republicans, Democrats among Democrats. Attitudes, migrations and congressional redistricting made this possible. The so-called "landslide county" is a measure of that change. In 1976, for example, only about a quarter of American voters lived in a county where a presidential candidate won by a landslide. By 2008, nearly half of us lived in such counties. Last year, I would not have bet against that trend. But in 2016, with Trump in the picture, all bets are off.
