Important looking letter from "The Office of Records" of the Assessment office of this or that state. Stamped "Notice of Delinquency" in red. (If it were from a collection agency that would be actionable, right there. Debt collectors are not permitted to state or imply on the envelope that there is a debt.)
Turns out to be a request for a donation, machine-signed by Reince Priebus, Chairman, Republican National Committee.
As Festus phrased it, "it was mighty thoughty" of the RNC to send that out to the faithful who were not faithful enough to have sent in money recently; shame the heck outta them, that'll get them to ante up.
What's next? A fake court summons? Notice of unpaid child support?
The RNC needs to clean house, fire Priebus. Or merge with the NRA that has run a successful scam for years, let Wayne LaPierre run the party.
