The Oklahoma Constitution specifically states that only one state senator can be elected as president "pro tempore". To address the historic tie, a power sharing agreement was reached that created the "co-president "pro tempore"." Under this agreement, Democratic State Senator Mike Morgan of Stillwater served as the president "pro tempore" of the Senate and Republican State Senator Glenn Coffee of Oklahoma City served as co-president "pro tempore". Coffee switched places with Morgan for one month, July 2007, to symbolize the unity between the two parties. While Coffee held the office of president "pro tempore" in July, Morgan served as the co-president "pro tempore".
