Actually, a more concise and potent statement would be:
“Dear Soon-to-be-Former Congressman,
Your vote yesterday was a disgrace to a free America. I avidly look forward to making you “Primary Dead Meat” come your next run-up to Congress.”
F@ck You Very Much,
John Q. Citizen”
Psssst. There’s a black Suburban parked across the street :-) you said “dead”
