Newly-elected County Mayor Tim Stribling was named chairman of the county commission Monday night, and Seventh District Commissioner Larry Summers was returned as chairman pro tem. The commissioners must elect a chairman and a chairman pro tem every year, and while the county mayor or a commissioner may be elected chairman, the county mayor must be chairman to break a tie vote, and may not vote otherwise. If a member is elected chairman he may votes as a commissioner, but cannot vote to break a tie.
