Members of Congress can serve unlimited numbers of terms if they are reelected. Is this consistent with the principles of representative democracy and limited government? Why or why not?

This does not really adhere to the principles of representative democracy and limited government. This is because even if the freedom to vote is exercised, voters still do not have a choice if the person ran again for the same position and no one's contesting this re-election. All members of the congress should be given fair share or equal rights to be in position.
