It’s not product placement. Trump’s campaign staff is making a vain attempt to get Trump to talk about the issues rather than all the ineffective personal attacks and name calling.
They’ve been writing speeches to get Trump to talk about inflation. This time they added some props to force him to talk about how these items cost more now. Of course Trump only spent a few minutes saying something vague about inflation and then regressed back to his typical ramblings about how if Kamala gets elected the world will end or whatever.
Ideally this kind of message would work better if Trump was in a grocery store, but he doesn’t venture from his two homes very often these days, so they set up a table in front of his Golf course so he could talk about it there. So it looks like product placement, but it’s just a vain attempt to get Trump to deliver some kind of economic message.
