I have noticed something else that may be significant in the some recent polls: The number of undecided voters seems to be increasing, rather than decreasing as it tends to do when nominees are determined.
This could result from cross-pressures. Majorities of voters have unfavorable feelings toward both candidates, and probably a record share, about 25 percent, has unfavorable feelings toward both. Apparently some voters are having trouble deciding which repellent candidate to vote for.Bingo. Well, not to exaggerate: I'm not having trouble deciding, just trouble stomaching my decision.
