“Should the group in a legislator’s district that got him elected monitor his votes, and recruit someone to run against him in the next primary if he starts voting wrong?”
I believe that there should always be a group of people monitoring the voting. No one should be allowed to use someone else’s vote in favor of his or herself. I also believe that recruiting someone else to run against him or her in the next primary only if he or she begins voting wrong, is a very unprofessional way of dealing with these types of problems.
The solution I would give is to eliminate anyone using someone else’s votes to favor his or herself.
In conclusion, yes, the votes should be monitored, but in a truthful way.
