Just to add-- if 23 of 30 owners vote to take away the Giants rights to the territory, the A's can just move. A vote has not been called for because Athletics ownership don't think they have the votes. This voting process could work for the Rays in the future. There has to be a few owners out there who wouldn't mind seeing the spending power of the Yankees and Mets cut into.
Sternberg might be able to get 23 votes. He'd have at least 1 from Oakland but lose 1 from San Francisco. He could probably also count on Toronto, Boston, Baltimore, Atlanta, Miami, Washington, and his own vote. Philly would be on the fence. That's 8 yes, 3 no, a big maybe and 18 question marks.
