It sounds like the scam was possible because of shortcomings on the part of the tRump campaign, not because of the lack of critical thinking skills of the people giving money - or rather, the lack of critical thinking skills on the part of the donors was indicated by who they intended to give money to, rather than falling for the scam. Really, the ideal situation would have been that the donors never knew it was a scam - it would have been just as useful, politically, and the money wouldn’t have been used to enrich tRump via his own campaign scam.
That’s the problem, isn’t it - if tRump’s name is being used, whether or not he’s actually involved, it’s a scam either way.
