Even after he put all the charges on the Senate (taxpayer) credit card, a matter of public record.
The problem with some credit cards is they are dual purpose and intended to be that way. I had an employer where the card could be used for personal and company expenses, with me being primarily liable, but able to be reimbursed for company expenses. A bad thing, but the way they did it. The point is that credit card transactions can n be confused and confusing; thus, not a good thing to use, by themselves, against any candidate. It’s far better to go after Rube for his horrible dishonesty on immigration, not credit card garbage.
To clarify, it was a state Republican Party credit card, when he was in the Florida legislature. So, it's more ripping off GOP donors than taxpayers, unless you believe it was just an accident or convenience and he always intended to pay it all back it was just in the newspapers first...
