(2) Each member of the general assembly, before he enters upon his official duties, shall take an oath or affirmation to support the constitution of the United States and of the state of Colorado and to faithfully perform the duties of his office according to the best of his ability. This oath or affirmation shall be administered in the chamber of the house to which the member has been elected.

The person appointed to fill the vacancy shall be a member of the same political party, if any, as the person whose termination of membership in the general assembly created the vacancy.
