Enlighten me.
Which unions?
There are over 175,000 voting precincts in the US. How do the unions go about controlling the audits/recounts in each of them?
How do the union bosses make sure the tens of thousands of members who have to be involved in the fraud keep silent?
Why should I need to? I would think most people having discussions on this forum would have some understanding of the history of Labor Unions in America and the corrupt behaviors they have exhibited in the past.

I could take a stab and say "all of them."

They don't need to do that. They only have to control the bottlenecks which are the major cities with corrupt election officials.
We clearly don't have a fraud problem in areas outside of major cities.

Again, you don't seem to have any familiarity with the history of Unions or their tactics. They will in fact kill people.
