Congress has not passed a full budget in 3 years. There are currently over 200 Presidential nominations awaiting Senate approval.
If normal citizens are negligent at their jobs, their jobs are terminated--Congress should not be exempt from this principle. Voters should keep their elected officials accountable at the ballot box, however for a variety of reasons our electoral system is fundamentally broken.
Every year, all Congressional members should be dismissed from congress and banned from re-election if they are unable to do their jobs and pass a budget or vote on Presidential nominations.
This would allow a fresh set of elected officials to join Congress, and perhaps this new set of individuals would be able to work together effectively.
