According to a Reuters story, presumptive Republican Presidential nominee Senator John McCain would make say-on-pay shareholder votes mandatory if elected:

"Americans are right to be offended when the extravagant salaries and severance deals of CEOs ... bear no relation to the success of the company or the wishes of shareholders," he says, adding that some of those chief executives helped bring on the country's housing crisis and market troubles.

"If I am elected president, I intend to see that wrongdoing of this kind is called to account by federal prosecutors. And under my reforms, all aspects of a CEO's pay, including any severance arrangements, must be approved by shareholders," he says.
