Polling review for 2016 and 2018 and a look forward to 2020

Mike Noble, chief of research and managing partner of OH Predictive Insights, has put together polling data looking back at the past two elections and looking forward to the next. Noble has dug up data that shows Senator Kirsten Sinema was able to flip precincts where Trump won before but Martha McSally was not as successful in that. His polling also shows Trump beating every Democrat in Arizona except Joe Biden. We get more from Noble on his polling data.
