This is so sad on so many levels. The biggest is that millions of people like yourself are so infected with TDS that you'd blame such a situation on Trump and spread such falsehoods claiming the Trump campaign made this poor guy lose his life savings.
No, the gentleman has dementia/Alzheimer's (or some other variant which acts the same way) and his daughter/son are attempting to shift the blame for this horrible disease and their utter failures to deal with the realities of it to someone else where they conveniently have a willing audience on CNN. The family is responsible for not taking steps to address the situation. Period. No amount of shifting of the blame and deflection will make that not the case.
It's a terrible thing, but you deal with it rather than playing ostrich. Had they done what was appropriate, this man would not have spent money with anyone that he shouldn't have. He signed up for recurring charges. And the family allowed that to happen. After the horse is out of the barn, it's too late to undo and you can't blame automated systems which the guy willingly signed up for and approved. He could have done the same thing with a prince in Nigeria, dogs and cats being rescued, or the CBS record and tape club. Not one iota of information there suggests that the "campaign" did anything wrong other than they accepted regular donations from the guy. The family should have cut it off and not allowed it to happen. They were either in denial or asleep at the wheel.
We've had to deal with this multiple times within my family and it sucks. But, when my grandmother left a cast iron skillet on the stovetop and my cousin walked in to find it glowing red, we didn't blame GE or Lowe's for selling her an electric stove or Duke Power for providing electricity to her house. We simply removed the pigtail so she wasn't able to burn down the house the next time she forgot about a pan.
Your issues with Trump have nothing to do with this poor man and his disease/decline. It's so sad that you'd take advantage of his plight to push such an agenda. Further, it wasn't Trump's campaign, but WinRed. Ever heard of ActBlue? Sure, they're both paragons of virtue.
Lastly, have you looked at the person sitting in the Oval Office the last two or three years? The "family" stepped in to take care of that situation like they should have and told him to have a seat. The problem is, they left him sitting behind the Resolute Desk instead of telling him to permanently take a seat at the beach in Rehoboth. Claiming this was all on Trump is actually a great example of the real issue being presented to the voters and a great illustration of the lies that have been sold about KH and the agenda. It couldn't be more clear, but you can't see it through the orange fog in which you exist.
