“that I will well and faithfully discharge the duties of the office on which I am about to enter”
The fact that they have gone to great lengths to IGNORE their constituents on the Amnesty bill I think is not a faithful discharge of their duties.
This is a Republic, not a democracy. It is not one of their duties to do what their constituents want them to do. Their constituents elected them to exercise independent judgment, and if their constituents dislike the judgment that they have exercised, they can vote them out of office.
