About this Poll
The Monmouth University Poll was sponsored and conducted by the Monmouth University Polling Institute from August 26 to 29, 2016 with a random sample of 402 likely Pennsylvania voters. Interviews were conducted by a live caller in English, including 351 drawn from a list of registered voters (200 landline / 151 cell phone) and a random digit dial supplement of 51 cell phone interviews. [...] For results based on this sample, one can say with 95% confidence that the error attributable to sampling has a maximum margin of plus or minus 4.9 percentage points (unadjusted for sample design).
