3:17 PM PT -- 7/15 -- Brittany Yanick, Communications Director for Dr. Oz for Senate tells TMZ ... "It makes sense that John Fetterman was able to have a member of the 'Jersey Shore' cast record a video for him - he was just there vacationing, but he can't make time to face voters on the campaign trail or do interviews.”
Snooki may not have realized a recent Cameo she recorded was for Dr. Oz, but you gotta admit, Oz's opponent was pretty clever in getting the "Jersey Shore" involved in his campaign.
The video starts with a friendly "Hey Mehmet!" -- Oz's first name -- from Snooki before she says she heard he had recently moved from New Jersey to Pennsylvania to "look for a new job." Snooki says she's confused as to why anyone would want to leave Jersey at all.
