By Jim EllisJuly 31, 2020 — Two survey research organizations, Morning Consult and Change Research, just released the results of their recent battleground states polling series. Looking at all the recent public data in these places illustrates the polling volatility and movement within the states that will ultimately decide the presidential election.
The ballot test results listed for each state below illustrates the most extreme examples for President Trump and former vice president Joe Biden during the mid to late July period. With such a wide variance in most places, it is difficult to say with any certainty exactly how these defining states will actually perform come Election Day.It is also important to take into account sample size, sample segmentation, and whether the poll was conducted through live interview, online questioning, or an interactive voice response system.
• Morning Consult (JULY 17-26, 908 likely Arizona voters)
Joe Biden (D) ………….. 49% (+7)
Donald Trump (R) ……. 42%
• Change Research (July 24-26, 365 likely Arizona voters; targeted online sample)
Joe Biden (D) ………….. 47% (+2)
Donald Trump (R) ……. 45%
Arizona surveys have consistently yielded small leads for Biden over the past several months. Most of the recent results find the candidates falling within the polling margin of error.
• Morning Consult (July 17-26, 3,593 likely Florida voters; online)
Donald Trump (R) ……. 48% (+1)
Joe Biden (D) ………….. 47%
• Quinnipiac University (July 16-20, 924 registered Florida voters; live interview)
Joe Biden (D) ………….. 51% (+13)
Donald Trump (R) ……. 38%
This is the most divergent spread within all of the battleground states. Florida’s polling history has routinely featured wide polling ranges that result in close election results.
