I would take the opposite side of this bet. I don't think she'll run for president. She has too many skeletons in her closet, especially related to protecting Bobby Kotick.
She may be more clean than they are, but they convinced their voters that they're ethical people -- or at least ethical enough. And all of them (except Trump) started with a clean slate in their first election, before running for president.
Sandberg is starting from a bad spot. She has all the liabilities of Clinton without the decades of campaigning to give her a base of support.
