Dr. Edward Shadid, 43, a spinal surgeon, was elected to the city council of Oklahoma City on April 5, 2011. The election was non-partisan. He had run for the legislature as a Green Party nominee in 2010, and had polled 10.5% in a race against a Democrat and a Republican. Because the Green Party has never been on the ballot, he was on the 2010 ballot as an independent.
Here is a news story about his winning a seat on the city council last month. Several hundred thousand dollars in independent expenditures were spent against him, but he still won the April run-off with 62% of the vote. UPDATE: he is a registered Independent, according to the Oklahoma County Election Board. the newspaper story is incorrect when it says he is a Democrat. Neither he, nor anyone else in Oklahoma, is permitted to be registered “Green”.
