Members of Congress will have less time in office to develop financially beneficial commitments to lobbyists and other special interest groups, thereby undermining the threat of lobbyists being a primary influence on legislation.
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. Congress would have an easier time passing the legislation that would make a positive difference for the nation.
