The 2006 Connecticut gubernatorial election occurred on November 7, 2006. Incumbent Republican Jodi Rell became governor when John G. Rowland resigned on corruption charges in 2004. Rell had an approval rating of 70% as of October 19, 2006, and polls showed her leading the Democratic nominee, New Haven mayor John DeStefano by a near 30-point margin. As expected, she won the election to a full term in a landslide. DeStefano defeated Stamford Mayor Dannel Malloy in the Connecticut Democratic gubernatorial primary on August 8. As of 2026, this is the last time a Republican and woman was elected Governor of Connecticut, and the last time any gubernatorial candidate won every county in the state to date.
