Merrill released the results of a new poll, in which participants from Arizona were asked who they would vote for. Of those who answered the question, 38.0% said that they will vote for Hillary Clinton, whereas 38.0% said that they would give their vote to Donald Trump. The poll was in the field between March 7 and March 11. The sample size was 701 likely voters. Figures have a +/-3.7 percentage points error margin.
Translating these results into two-party vote shares yields values of 50.0% for the Democrats and 50.0% for the Republicans.
