POLITICAL REF'S AVG:

Harris 47.6, Trump 47.6
Sample Size: 10,073 Voters
Theoretical Margin of Error: 1.0%
Sample Model: 2020 Exit Poll Turnout Model (Polls that did not use 2020 Exit Poll were adapted to it, which justifies a margin of error).
EXIT POLL & 2024 TURNOUT ASSUMPTIONS
POLLSTERS:
Harris +0.4
Harris 47.7, Trump 47.3
Susquehanna Poll from 10/23-10/27 is excluded because it did not provide cross-tabs and the poll had an extreme bias, click here.
CNN/SSRS last Michigan poll is excluded as an outlier. My goal is accuracy and a poll showing Harris tied with men and winning Independents by 30 will not contribute to that goal.
If a poll is missing, it does not release cross tabs, has too small a sample (<500) or averaged 3 or more off the result in the last two presidential elections. Outliers will be excluded if its the last poll.

Far too many Dems and far too many college and post-grad degrees, severe pro-Harris biases not offset by pro-Trump biases. Will adjust.

A pro-Trump bias,too few women was offset by slightly too many college and post-grad degrees and far too many 18-29, a pro-Harris age group, along with too few 50-64 and 65+ age groups, pro-Trump age groups. Because the Washington Post did not provide cross-tabs for Michigan specifically, I must make an imprecise adjustment. A bias of this size will typically yield about a 1 point net change, or 0.5 points in each direction. Harris 48.5. Trump 47.5 +1.0   x

Political Ref's Take Poll Bias Score -6, no bias, included in my average. In a surprise, I had no problem making sense of the Quinnipiac internal data. When the pollster includes all racial vote data, meaning vote ratios including Latinos and Asians, the data adds up. I can infer the education ID when all racial vote data is provided. When it's not I have to start assuming things. Just speculating, but perhaps QU wanted a certain result in Pennsylvania and made the data fit raising the need to hide Latino and Asian data? The profoundly pro-Trump gender gap in Michigan made it futile to try and get a desired result. I do not trust Quinnipiac because their final results often grossly favor Dems and they lack sufficient transparency. Harris 47, Trump 50     x

Political Ref's Take Poll Bias Score 107 towards Dems. Severe bias, will adjust all categories and average with original topline.

Political Ref's Take Poll Bias Score 302 to Dems. Will adjust. The bias comes almost completely from a severe education bias that is not balanced by any other bias. I had to infer the actual education ID, but the numbers show a larger lead than 1 for Trump, much more in line with a 3-point lead. Additionally, the numbers show between a 7 to 15-point lead for Trump among Independents, and Republicans and Democrats are likely to have equal turnout. This adjusted result is what the numbers support. Adjusted poll bias score is 36, or insignificant bias. See calculations here. Harris 47.0, Trump 50.1     x

Political Ref's Take Poll bias score of 310 toward Dems, a severe bias that must be adjusted in three areas. Recall that I only adjust until the poll balances, so we are getting the poll to a non-biased place. The poll assumed a 62/37 F/M split, 60/40 No BA/BA+ education split and 67/33 White/Non-White split. Correcting for all three and averaging the results together gave Harris 49.7 to Trump 47.6.
