Constitutional positions are being filled on the national and state levels.
Section 2 of Article 1 of the U.S. Constitution, near the end, states that "The House of Representatives shall chuse their Speaker and other Officers." It doesn't state how, or even that the Speaker need be a member of the House. The Texas Constitution also creates a Speaker to provide over the Texas House in Section 9 of Article 3, but does stipulte that the Speaker be a member of the House.
The office was based on a similar position in the British House of Commons.
Though the Speaker of the House of Commons is a non-partisan moderator of debate, as parties developed in Congress, the position became politicized. We have Henry Clay to credit or blame for that development.
