For political observers, 2016 feels like an earthquake — a once-in-a-generation event that will remake American politics. The Republican party is fracturing around support for Donald Trump. An avowed socialist has made an insurgent challenge for the Democratic Party’s nomination. On left and right, it feels as though a new era is beginning.
And a new era is beginning, but not in the way most people think. Though this election feels like the beginning of a partisan realignment, it’s actually the end of one. The partisan coalitions that defined the Democratic and Republican parties for decades in the middle of the twentieth century broke apart long ago; over the past half century, their component voting blocs — ideological, demographic, economic, geographic, cultural — have reshuffled. The reassembling of new Democratic and Republican coalitions is nearly finished.
What we’re seeing this year is the beginning of a policy realignment, when those new partisan coalitions decide which ideas and beliefs they stand for — when, in essence, the party platforms catch up to the shift in party voters that has already happened. The type of conservatism long championed by the Republican Party was destined to fall as soon as a candidate came along who could rally its voters without being beholden to its donors, experts and pundits. The future is being built before our eyes, with far-reaching consequences for every facet of American politics.
