I'm not sure how common this practice is, but it sure calls into question the value of political endorsements. After dropping out of the race, former Iowa Governor Tom Vilsack has agreed to endorse Hillary Clinton; in a completely unrelated matter, Hillary Clinton has offered to pay off Vilsack's campaign debt.
Former Iowa Gov. Tom Vilsack gave Sen. Hillary Clinton his endorsement for her presidential campaign.
The Clinton campaign has promised Vilsack to help pay off a $400,000 campaign debt he built up during his run for the White House.
A representative for Clinton's campaign said they are not sure how their campaign will do that. They concede that at some point, Clinton will have to contact her supporters.
The campaign said there is no connection between Vilsack's endorsement and their commitment to help pay off his campaign debt.
That Clinton's representative didn't know how they'd do it indicates to me that this practice isn't too common. In any event, I'm not going to weight Vilsack's endorsement too highly.
