I realize that this is a bit complicated for Trump supporters to understand, so please read it carefully and try to understand it before replying:
An elected official is generally supposed to represent the will of their constituency - the people who voted for them, the people who voted against them and the people who did not vote. Since the majority voted for them, they should weigh in favor of that majority.
However, that is only true to the extent that it is in keeping with their Oath of Office and any other official Oaths that they've taken per their office.
In this case their Oath taken as U.S. Senator and the Oath taken at the beginning of the impeachment trial overrides any obligation to their constituency.
In fact
if they violate these oaths they should be removed from office - regardless of the will of their constituency.
" I
do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter: So help me God.
I solemnly swear (or affirm, as the case may be) that in all things appertaining to the trial of the impeachment of (the president’s name), President of the United States, now pending, I will do impartial justice according to the Constitution and laws: so help me God.”
43 U.S. Senators have befouled their oath of office and their Impeachment Oath and should be removed from office!!!!
