To upset Barack Obama next Tuesday, John McCain is counting on a conservative base in small towns, energized by running-mate Sarah Palin. It's the so-called "values vote," focused on social issues -- abortion, gay marriage and gun rights -- as well as cutting the size of government. Four years ago, Thomas Frank published What's the Matter with Kansas?, raising a question about the so-called "values voters" who were crucial to the election and re-election of George W. Bush. This year, big parts of America's "Heartland" have become battlegrounds between McCain and Obama. Is that a temporary phenomenon or will there be lasting political consequences? Is the economy trumping the culture wars? Has the population changed in the past eight years?
