DES MOINES, Iowa – For nearly a half-century, the Iowa caucuses have kicked off the presidential nominating calendar.
And while their record of picking presidents is inconsistent, the winner of the caucuses has gone on to win their party’s nomination more than half the time.
2020 PRIMER: HOW THE IOWA CAUCUSES WORK
Only three caucus winners – Democrats Jimmy Carter in 1976, Barack Obama in 2008 and Republican George W. Bush in 2000 – went on to win the White House.
But the caucus winners have a better batting average when it comes to winning the presidential nomination – at least on the Democrats' side.
Seven of 10 Democratic caucus winners have gone on to become their party’s standard-bearer. Just three winners of the eight contested GOP caucuses eventually won the Republican nomination.
