How about Isara.
He was here for four months plus Hawking Cuz with flat out disinformation supplied by levin.
The day of the Iowa caucus he up and left the form out of the blue.
No one will convince me he wasn’t here under contract.
The timing is suspicious. After each primary the state campaign shuts down within hours. Real people keep talking up their candidate even after their state votes. A paid Iowa caucus campaign troll would match the pattern you observed.
That pattern is a pretty good filter for spotting trolls.
