Is Iowa for Winners?
Earlier this month, Haley caught some flack for seeming to disparage the ability of Iowans to pick presidents, joking on the campaign trail that while "Iowa starts it, [New Hampshire] corrects it."
While Haley's remark might cost her politically — DeSantis brought it up multiple times in last week's debate and featured it in his closing Iowa ad — she isn't exactly wrong about Iowa's track record, especially in recent years. It's been over two decades since the winner of a contested Iowa caucus has gone on to win the GOP nomination and the presidency. That was George W. Bush, who won 41 percent of the caucus vote in 2000. Since then, no Iowa caucus winner has won the GOP nomination, let alone the White House. Mike Huckabee in 2008, Rick Santorum in 2012 and Ted Cruz in 2016 were all the runners-up in their respective primary races despite making an early splash in Iowa. Overall, in the eight contested Iowa Republican caucuses since 1976, the winners have only gone on to claim the nomination three times.
Candidates who have won the Iowa caucuses but not presidency
The state is actually far better at picking Democratic nominees: 2020 was the first time since 1992 that the winner of the caucus (either Pete Buttigieg or Bernie Sanders) didn't go on to win the nomination. Of course, that track record wasn't enough to convince the party to keep Iowa as the first-in-the-nation contest this year.
