I think it's complete bs. how is it people haven't already decided who they're going to vote for.
I'd agree that there is a large group ( a third?) that do not vote for whatever reason But to say that there are still undecided voters that Trump needs to sway is nonsense. There's really nothing he could say or do to get these do called undecided voters to vote for him.
By the way, in the farcical Biden town hall meeting the so called undecided voters had actually previously said they were voting for Biden. what a load of bs.
There is no one that stupid to be undecided at this point.
