Term limits should be imposed. Too often politicians lose sight of what really matters: the people they serve. Career politicians become obsessed with re-election. Since they have the funding for campaigns that others do not, they most likely win even though they are not the best choice.
Congress is heavily entrenched in partisan politics, resulting in gridlock when trying to pass any legislation. If term limits were enacted, toeing the party line would be less important, as the need for re-election and holding onto party seats would no longer be the driving force behind most legislative decisions.
Too much power can often corrupt and we see this time and time again in Congress. It's time to limit their power.
