In the past seven months of the Republican presidential campaign, there have been more than a dozen debates and countless polls. Nearly every candidate has enjoyed the spotlight as a front-runner.
Today, the nominating process kicks off in earnest as Iowans gather in schools, churches and neighbors' homes to vote.
Having covered caucus campaigns since 1976 for the Des Moines Register, I'd like to clear up some misconceptions about Iowa voters and the state's role in the race for the White House:
1. Iowa voters don't represent the United States.
Not all New Yorkers are rude, not all San Franciscans are gay, and not all Iowans are farmers.
Of Iowa's 3 million people, about 90,000 are farmers, and of those, 48,737 list farming as a principal occupation. Iowa's manufacturing and financial services industries contribute far more to the gross state product than does farming.
So media caricatures of snaggle-toothed hicks from an "American Gothic" painting don't fit.
The state is 91.3 percent white, while the country is 72.4 percent white. But even these homogeneous demographics helped Barack Obama when he won the 2008 Democratic caucuses.
