There's a bunch of em...look at this recent poll in Utah.
That graphic seems pretty normal. 1/3 of the nation will vote D, no matter what. 1/3 will vote R, no matter what. 1/3 want to procrastinate and wait a while longer to see how things go. And 1/3 of each of those categories will remain squishy for a while. Those numbers shouldn’t change much over the next 4 months, and should be expected to have been seen at this point in every election over the past 30 years.
