A little swing music: are "Office Park Dads" for real? Karlyn Bowman introduces us to the latest voting blocks a pol must reach to win.

I BLAME IT ALL on my colleague and friend at the American Enterprise Institute (AEI), Ben Wattenberg. In 1970, he and Richard Scammon published The Real Majority, a book that quickly became a classic in psephology. In it, they identified the "Dayton housewife" and her concerns about social issues as the key to understanding the American electorate and winning elections. In virtually every election since, one group or another has been described as the key to victory.
