That’s interesting why so many of them share the same P.O. box. I wonder if it is like some type of mini zip code?

I'm guessing it's some sort of business that handles the nuts and bolts of PAC donations for a fee. Sort of like a re-mailing company.

They probably have accounts with dozens of different PAC organizations, all of whom pay them to do the grunt work for them.

“I’m guessing it’s some sort of business that handles the nuts and bolts of PAC donations”

That makes sense. I imagine a lot of these PACS are short-term; for an election or two. So they just come up with the idea and let the experts handle the money. Hmm - I suppose a lot of the production for the ads and mailings are also shared - XYZ Advertising handles multiple PACS.
