I saw this on a Rumble comment. Sounds like a GREAT idea!

CALLING ALL PATRIOTS! Presidents day is Monday Feb 15th. Send President Trump a handwritten postcard expressing your gratitude, support and wishes. Imagine the visual of 75+ million pieces of mail being delivered. PASS IT ON.

President Donald J. Trump
