Two public employments can lead to corruption
The constitution of the United States of America prohibits a federal office holder from being a member of congress in Article 1 Section 6, the Second Clause:
“No Senator or representative shall, during the time for which he was elected, be appointed to any civil office under the authority of the United States, which shall have been created, or the emoluments whereof shall have been encreased (sic) during such time; and no person holding any office under the United States, shall be a member of either House during his continuance in office.”
This clause was included in our constitution to prevent mischief.
This restriction is not incumbent on the states. In the states, the state legislatures control the attributes, structures, responsibilities, and privileges of the counties and cities in the states. That is in Washington State the counties and cities are subsidiaries of the government of the state.
I was surprised to find out that our state constitution does not include good sense restrictions analogous to the wisdom of the founding fathers. The Washington State Constitution should include restrictions disallowing state legislators from having any other public office with the state, counties or cities.
As the Washington State Legislators are part-time legislators, their remuneration is not sufficient to provide some legislators enough to live on. So I understand why state legislators, despite possible conflicts of interest, are allowed private employment while serving. However, the employment should exclude other public employment. In general, having two public employments does not lead to good, honest government. Instead, it provides an opportunity for corruption.
