Three days after the Iowa caucuses, the state Democratic party at last released all of the results, showing the tightest of races between Pete Buttigieg, former mayor of South Bend, Indiana, and Sen. Bernie Sanders, I-Vt.

About 6 in 10 Democrats at the Iowa caucuses on Monday reported that they support eliminating private health insurance as part of establishing a single-payer health-care system, according to preliminary poll results, suggesting that most of the party's voters agree with Sen. Bernie Sanders, I-Vt., on the divisive issue.
