The Clintons are slick. Most every crooked dollar they get goes into their foundation where they don’t have the same kinds of tax implications as does the foundation.
They have control over a very large sum of money, the perks and benefits from it, and little personal liability. It’s really a sweet deal if you can get something like that.
As for WalMart and the pros or cons of the association they have or had with any of the Clintons, I’d chalk it up to bidness. Clintons would take money from anybody.
