Serving in Congress should not be considered a "lifetime" career, nor should one individual be allowed to monopolize an office. It's time to put country first over personal political ambition. Two term limitation allows Congressional representatives to be our "voice" for a specific time period, take action, and move on so other citizens can have their chance to serve.
Why is this important?
Tired of obstruction and delay in Congress? Limiting Representatives and Senators to TWO TERMS motivates those in office to actually "do" something. Added bonus: eliminates the creation of political "dynasties."
