Buried beneath the new horserace numbers coming from the Quinnipiac poll released today of 1,572 likely Minnesota voters is even more sobering news for President George W. Bush (and, perhaps, John McCain) as he finishes his second term: Bush’s approval rating has dipped to an all-time record low of 24 percent in the Gopher State, with an all-time record high 70 percent disapproving of Bush’s job performance.

Bush’s approval rating had dipped below 30 percent five times during the past year (in SurveyUSA’s monthly polling series), but never below 28 percent. Bush’s disapproval rating had previously peaked at 69 percent in September 2007. Presidential coattails for McCain? Nary a stitch of clothing to be found.
