It seems clear that the very opposite of the editorial's last sentence is true:  The Clinton Foundation's real and only causes for existence were precisely because of Hillary's previous and future runs for the White House - and because of the Clintons' desire to (1) keep all their hangers-on (chief among them, daughter Chelsea) grandly employed while they all helped her run for President and (2) so that the whole apparatus could be used to sell influence and make money for the Clinton's themselves.

When you look at the success they have had with all of that, you have to conclude that the scheme succeeded beyond expectations.  That success is thoroughly without precedent.
