From DailyKos.com and many other sources:
On March 15th, each of us will mail Donald Trump a postcard that publicly expresses our opposition to him. And we, in vast numbers, from all corners of the world, will overwhelm the man with his unpopularity and failure. We will show the media and the politicians what standing with him — and against us — means. And most importantly, we will bury the White House post office in pink slips, all informing Donnie that he’s fired.
Each of us — every protester from every march, each congress calling citizen, every boycotter, volunteer, donor, and petition signer — if each of us writes even a single postcard and we put them all in the mail on the same day, March 15th, well: you do the math.
No alternative fact or Russian translation will explain away our record-breaking, officially-verifiable, warehouse-filling flood of fury. ASK HIM ABOUT HIS TAX RETURNS. Hank Aaron currently holds the record for fan mail, having received 900,000 pieces in a year. We’re setting a new record: over a million pieces in a day, with not a single nice thing to say.
So sharpen your wit, unsheathe your writing implements, and see if your sincerest ill-wishes can pierce Donald’s famously thin skin.
On March 15th, mail your messages to:
President Donald J. Trump
The White House
1600 Pennsylvania Avenue NW
Washington, DC 20500
