The truth is, would-be presidents don't always care about the issues that turn out to be most important. How did Bush flip his foreign policy views so easily? By not having strong convictions on global affairs in the first place, allowing neoconservative advisers to fill the void after the 9/11 attacks. It's easy to imagine, say, John McCain doing something similar during an economic crisis, given that he has already radically reinvented his economic philosophy twice in the last decade, shifting leftwards in 2000 and back to the right in 2008.
