Here is a better option to poll watching. Become an election judge. I did so years ago, and I am directly involved in ensuring fair and accurate elections. Poll watching is just a waste of resources. You are much better off being directly involved in the process.
In Texas, you can only place a Republican Presiding Judge in a Republican majority precinct. Almost all of the fraud is in the dim precincts with no Republicans to catch them.
The Poll Watchers are there to back up the Republican Alternate Judge.
For example, there is fraud at the Sign In Desk when the dim Clerks let someone vote without a Voter Registration Card, vote in the wrong precinct, or without ID when voting for the first time.
At the same instant, someone has to watch the dim Clerks running the Judge’s Ballot Computer. There have been cases where the Clerk will print out 5, 10, or 20 Access Codes for the ESlate voting machine. When his buddy, the dim activist, comes through the line HE HANDS HIM EXTRA ACCESS CODES. By voting straight ticket, it is possible for the scam artist to vote many times without being caught. Imagine how easy it is to slip your buddy enough access codes to vote multiple times!
I agree, we need more Republican Presiding Judges and Alternate Judges, but after filling those slots, we MUST back them up with Poll Watchers. One person cannot observe the entire polling place.
