Update. While poking around at Conservative Treehouse, came on this very interesting comment. Did Breitbart just miss this?

Both PAC’s (along with many campaigns and PAC) use the services of Chris Marston and his company Election CFO. That is their address. Note that the FEC filings for both PACs are signed by Martson, not because of some nefarious connections between them but because they both happened to use Martson’s company for their FEC filings and would use Election CFO’s PO Box for their official mailing address and also as the address to which to send donations as Election CFO provides banking and accounting services along with FEC compliance and reporting.

Here is a list of their clients in 2014 – the most recent year available on Open Secrets

One of those listed for instance – America’s First PAC and Liberty for All Super PAC (a Libertarian PAC), also lists Chris Marston as their treasurer and or PO BOX 26141, ALEXANDRIA, VA 22313 as their mailing address in their FEC filings
