One of the wacky things about the 750-voter, landline-only, five-day survey is how much partisan ID shifted in just a month. August’s poll was 46 percent GOP, 41 percent Democrat — the only major survey with a Republican plurality. This one is 48 percent Dem, 38 percent GOP.
Humphrey Institute Prof. Larry Jacobs ascribes this to renewed DFL enthusiasm. However, the dramatic shift will inflame the doubters, particularly GOP partisans, whose rightest wing generally regards the HHH poll as the junior member of a Strib-led pro-DFL Gruesome Twosome.
