George W. Bush left the White House with an approval rating hovering around 30 percent. Courtesy of his tenure, and his second term specifically, by 2008 large numbers of conservatives ceased to identify themselves as “Republican,” such was their shame. At least one million of them refused to vote for John McCain. But two years before this, their enthusiasm had already begun to wane considerably, for the Democrats hammered Bush’s party, regaining control once more of both chambers of Congress. By 2012, even fewer conservatives showed up at the polls to pull the lever for Mitt Romney.
