Incumbents generally have significant financial support to fend off those who would compete with them. If they are concerned about their actions while in office, let them spend these resources. It has long been the practice of political parties to back the incumbent — this practice should end prior to the primary vote. People have left the Republican Party due to the protections given to incumbents who, through their votes and actions, have circumvented the interests of their constituents. Competition is a central focus of our nation and should be the same for our political system — no one owns their elected position.
