Hillary Clinton and Donald Trump are effectively running neck and neck among likely voters in Arizona, according to the results of an Arizona Republic/Morrison/Cronkite poll released Wednesday, with more than one in five saying they are undecided about their decision in November.

Approximately 35 percent of the 704 likely voters surveyed said they would choose Clinton, while 34 percent opted for Trump, well within the poll's margin of error of plus or minus 3.3 percentage points. Another 23 percent said they had not decided, while Libertarian nominee Gary Johnson earned 7 percent and Green Party nominee Jill Stein had approximately 2 percent.


The poll was conducted via landlines and cell phones over a two-week period from Aug. 17-31, before the latest revelations from the FBI's investigation into Clinton's handling of classified information as secretary of state and as the Trump campaign retooled its management structure and messaging. Additionally, Trump's Mexico City meeting with President Enrique Peña Nieto and subsequent immigration speech in Phoenix occurred on the final day the survey was out in the field.

Trump has led in most recent polling from Arizona, including a CNN/ORC survey conducted Aug. 18-23, within the Arizona Republic poll's time frame, that found the Republican nominee in front by five points, 49 percent to 44 percent.
