No, it’s just a bullshit argument in this election. The electorate is viscerally polarized, and very few people are in the fence about who to vote for - maybe some undecided about whether they’ll vote at all. I can’t imagine there are many people who are going to switch from Biden to Trump because of this, or who will even go from undecided to Trump. It makes no sense.
On the other hand, Trump is going to fundraise the crap out of that picture, and it will squeeze lots more money out of his base.
