I was a bit puzzled by this as well. Don's guess about the path seems nuts but is more plausible than any of the alternatives. I suppose it's possible that, if they weren't so MAGA-fied to have believe this at face value immediately themselves, they hoped that Smith would be too baffled to respond.
Maybe I'm missing something, but I still don't get this. Schmitt was saying Smith went to a Hawks game. His evidence was texts that mention "Jack" but not from Smith (and the Hawks does not have a 109 row). Yes, Smith went to a Hawkeyes game, but Schmitt did not present any evidence of that.
