Does the OP know that a member of Congress does NOT have to live in the district they represent? Senators yes, they are required to live in the state they represent but NOT Congress.
But the OP, being the MAGA MAGGOT is lying. Swalwell does live in California. He was a City Councilman in California and a Deputy D.A. in California. The NY Post owned Murdock and lies every chance it gets.
Swalwell is NO longer in Congress, so the argument is mute. Also, under Congressional Rules, a mailing address is legal, did OP know that or the OP a full of shit MAGA MAGGOT.
