Mark Steyn makes my point (emphasis is mine):
The short version of electoral cycles is as follows: The low-turnout midterms are fought in political terms, and thus Republicans do well and sometimes spectacularly well (1994, 2010); the higher-turnout presidential elections are fought in broader cultural terms, and Republicans do poorly, because they’ve ceded most of the cultural space to the other side.
What’s more likely to determine the course of your nation’s destiny? A narrow focus on robocalls in selected Florida and New Hampshire counties every other fall? Or determining how all the great questions are framed from the classroom to the iPod to the movie screen in the 729 days between elections?
