Open Field: Voters Lack Signposts in this Election

"For a decade from 1995 to 2005, we operated in a period of trench-warfare politics, with two approximately equal-sized armies waging a culture war in which very small amounts of ground made the difference between victory and defeat. It was pretty clear what the major issues were, what strategies were necessary to win a party's nomination, how to maximize your side's turnout on election day (and, increasingly, in early voting). But times change. Somewhere between Hurricane Katrina in August 2005 and the bombing of the Samarra mosque in February 2006, I believe we entered a period of open-field politics, in which voters and candidates are moving around -- a field in which there are no familiar landmarks or new signposts."
