To figure out what was going on, I looked at a sample of 200 tweets using that phrase, and also purposively sampled the earliest tweets using that phrase to study its origins.
Immediately, the timing of the first 4 tweets using that phrase stood out to me. They were spaced out almost exactly an hour apart, nearly to the minute.
The jump from the 1st account, w/ 37 followers, to the 2nd account w/ 51,000+, to the 3rd — a GOP candidate for Atty General w/ 217,000+ followers — was eye-popping.
