President Obama was on for a second day of heavy campaigning in California on Monday, hitting San Francisco and urging supporters: "We're only going to do it if everybody is almost obsessive for the next 29 days."

Obama sounded that rousing note during an exclusive dinner at San Francisco's Bill Graham Civic Auditorium, urging his supporters to "mobilize every resource" they have "to make sure that we bring this home."

Millions of cable TV subscribers may have to buy or lease new converter boxes to continue watching some local stations in the wake of the U.S. Court of Appeals for the D.C. Circuit's refusal to intervene in an appeal of the FCC ruling.

As it stands, the viewability regulation is slated to expire December 12.
