All results in this section are from exit polls conducted for CNN by Edison Media Research and Mitofsky International. Interviews in the exit poll are conducted with voters as they leave the polling place immediately after voting. In some states, additional interviews are conducted by telephone with people who have cast an absentee vote or similar ballot.
Due to the unique nature of caucuses, polls in these races are conducted as caucus-goers enter the voting venue.
To illustrate how these results should be read, let's use the following hypothetical results as an illustration.
Vote by Gender
The first column of numbers shows how many people who voted today fell into each category. In our example, that means 39 percent of all voters were men and 61 percent were women.
All other figures show how each category voted. The numbers should be read across (which is why you may occasionally hear them referred to as "horizontal results"). In the example, that means that 52 percent of all men voted for Smith and 48 percent of all men voted for Jones. Looking at the next line, Jones won 53 percent of the women's vote to 47 percent for Smith.
