The Mercury News cites the “loophole” some in California are using to make political robocalls.

Robocalls that come from out-of-state call centers aren’t subject to the rule.

The vast majority of campaigns—if not all of them—use that tactic because the agency that oversees telephone communications, the California Public Utilities Commission, can regulate only calls initiated inside the state.

The commission does virtually nothing to enforce its own regulations.
