They can't really do that, though, unless they spend about half an hour with each respondent to get an accurate measure of his/her leanings and proclivities. Some broad criterion like who you voted for last time or what's your professed party or ideological affiliation won't cut it in this election.

 

Besides, I wasn't really talking about polls. I was referring to how Trump has virtually no way to increase the number who will vote for him, but Harris does. MAGA minds are already set in granite. In contrast, the vast majority of the undecided are not "Harris or Trump?", but rather, "Harris or stay home?"
