The latest Wisconsin poll from We Ask America doesn’t tell us anything new. Scott Walker remains unpopular, but not Rick Scott unpopular. I bring it up the new polling only to object to the decision to report the results with two digits after the decimal point. Nothing is gained by telling us that 45.15% of a 1300-person sample approves of Walker’s governorship. Nor does it help matters to warn of the 2.72% margin of error.
