The power to get rid of him will have to come from the financial institutions, or someone(s) rich enough to buy large amount of stocks (ie. Bass's). If Roy and gold (golden?) can convince enough of them to go along and win a proxy fight, then it will happen. That point may have not been reached yet, if ever.
What a lot of people don't realize is that the ultimate power comes from the stock holders and they don't bother to exercise their vote and let it default to the board. This is why a lot of CEOs stay in power. So next time get out there and VOTE!!
