Monitoring Politicians

Should the group in the 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?  Yes, I believe that the people do have the right to monitor the politician.  After all, they did vote for him to speak for the people and if the politician decides to start voting against what’s best for the people, then the group that voted for him should be able to send in someone to run against him, a person that will make better decisions for the public than what the person before him made.  In conclusion, I believe that the group that voted for the politician should be able to monitor his votes in case he votes against what he promised and, if necessary, recruit someone to run against him if he doesn’t vote on what’s best for the public.
