I agree with that. My biggest fear.
I could be wrong, you could be right, who knows.
But with Kanye, the discrediting of mail-in-ballots, the sabotaging of the Post Office, the welcoming of Russian Disinfo, the talk of delaying the election, the refusal to say that he will concede...
Trump doesn't seem as confident that these secret voters exist.
We'll see. I hope to be really wrong. My "knowledge" of secret Trump voters is hardly based on any scientific analysis but rather on the large group of people I know who quietly claim to not like Trump personally and do not even think he's done that great a job, but plan to vote for him anyway. Extrapolated to larger-sized groups and this is a big problem. One that I'm not certain polling can take into account. Not everybody is as obnoxious and obvious about their upcoming Trump vote as is Kid.
I am not sure that there is a significantly large number of secret Trump voters. His vote totals in 2016 were in line with his polling. If there was an issue in 2016 it probably had more to do with his opponent than undeclared Trumpists. That is why that Comey letter was such a dagger. "Jesus, four more years of THIS shit?" Kept people home, swung some voters at the end. I think Trump's people agree. Their entire strategy seems more aimed at suppressing Biden votes with negative campaigning than increasing their vote share.
When we start getting more "likely voter" polls, those might understate Trumpikely voters, because they seem now to be, not so much shrinking violet undeclared Trumpists, but loud, aggressive and pissed.
