Respondents who indicated that they would vote in or have already voted in the Democratic primary were asked, "In the 2016 Republican primary election for president, which of the following candidates did you vote for?" Response options were randomized. Respondents were first asked the question above. If they initially answered that they didn't know, they were then asked a follow-up question: "If you had to make a choice, who would you choose?" Responses to the follow-up questions were folded into the results found below. "Likely Voters" were defined as those who indicated that they were either "Extremely" or "Somewhat" interested in politics in Q2 AND either voted in "Every" or "Almost every" election in Q3. Measurement of Party ID for this figure is based on two questions. First, respondents were asked whether they consider themselves to be a Democrats, Republicans, independents, other, or not sure. Those who responded that they are independents or "other" were then asked if they lean toward either the Democrats or Republicans. If they indicated that they lean toward one party or the other, they are considered Democrats or Republicans for the purposes of this figure. Only "pure" independents or members of a third party who indicate that they have no preference for Democrats vis-a-vis Republicans are considered independents. Respondents who answered that they are "not sure" for either of the two aforementioned questions are not incorporated into this figure.
