i think that it is high time for the united states senate and its members to do some soul-searching—for us to weigh our consciences—on the manner in which we are performing our duty to the people of america—on the manner in which we are using or abusing our individual powers and privileges.

the us senate is abusing its power to manipulate the american people.
the us senate is performing its duty to the american people by soul-searching.
the us senate is using its power to enhance the american people’s well-being.
