Long ago and far away... Our union chairman wanted to run for local office and needed some number of signatures to qualify for the ballot. So his boys had a large ledger open on a table and when I came into work I was asked to sign three signatures on three different pages. I wasn't party to other illegal activities so there was no surprise at my declining the offer. Trump is a New Yorker as am I so he likely knows of voter tricks involving more than changing clothes. How can an ex union official not know of this? How can someone from Kennedyland not know of this?
Knowing something about dirty political tricks from the past is different than having the President make specific allegations about a specific person committing a felony and doing it all with absolutely no evidence.
