We have a right to sound government.
This section penalizes benefitting from political fraud or coercion, which covers any speech or conduct regarding an election, appointment, or Act of Congress or the Executive branch.
Article I, Section 5:
"Each House may determine the Rules of its Proceedings,
punish its Members for disorderly Behavior, and,
with the Concurrence of two-thirds, expel a Member."
Congress has the power of impeachment and expulsion:
they supervise all elected or appointed federal officers because they are the most closely accountable to the public.
Partisanship and private financing of elections make this supervision harder than it was designed to be. Impeachment is rare; expulsion has only been done once. Making political fraud, coercion and bribery impeachable or expulsible has become a needed clause.
"The United States will guarantee to every State fairly contested
and impartially conducted elections, monitored and audited. […]
The United States and every State will enforce the right
of a citizen eighteen years of age or older to vote, not to vote, or to abstain regarding any office or proposal, in United States or State elections."
Because any government interference with just governance, consent to governance, or the people’s exclusive right to ordain and establish government is such a grave offense, no privilege should conceal it from Congress. Existing rules require initiating expulsion proceedings in the same term in which the offense was committed, so the public must be alert and file grievances immediately.
Requiring Congress to take cases promptly also prevents delay until any decision is no longer relevant.
The impeachment and expulsion clauses, important enough to be expressed in Articles I, II, and III,
and in Amendment XIV, don’t grant power to fail to address them when needed.
Discretion is a power that is nowhere mentioned in the Constitution and would have to be,
especially for something as critical to the public interest as this.
Article II, Section 4:
“The President, Vice President and all civil Officers of the United States,
shall be removed from Office on Impeachment for, and Conviction of, Treason, Bribery
and other high Crimes and Misdemeanors.”
This section adds some detail to the grounds already listed in Article II, Section 4,
which already lists bribery as impeachable.
Because member speech or debate on the floor is exempt from prosecution
(Article I, Section 6: "they shall not be questioned in any other Place";
checks are discussed in Penalizing Political Fraud and the exception is discussed
for people to be questioned in Congress, the word "other" anticipates questioning in Congress.
Article I, Section 5 already provides for expulsion of members by their own house of Congress.
It should be noted that votes, Presidential acts and judicial opinions involve more than personal position.
