It was the first time since 1947 that four statewide elected officials were sworn-in during one ceremony in Oregon. Former Governor Barbara Roberts emceed the ceremony in the House Chambers in Salem. All four are known to lean to the left of the political spectrum.   Back in 1947, the re-elected Governor, the Superintendent of Schools, the Labor Commissioner and Secretary of State were all sworn-in at the same day. All four positions were elected on a partisan basis, and three of the four were Republican.
