At the same time he was signing the pro-Castro manifesto, Danny Glover was also flacking for long distance carrier MCI, and trading off his good guy image to get you and your family to buy MCI’s products.
That’s when we took action, by asking you to call MCI and let them know what you thought of Mr. Glover’s extreme political views.
You reached out and touched MCI, and other corporate heads listened.
