CHEYENNE, Wyo. (AP) — Cheyenne businessman Ed Murray has narrowly won the Republican primary for secretary of state.

Murray edged former House Speaker Ed Buchanan of Torrington by about 1,600 votes out of 89,000 cast.

No one ran in Tuesday's Democratic primary.

The GOP race became a free-for-all after incumbent Max Maxfield announced he would not seek a third term. Maxfield is stepping down despite winning a Wyoming Supreme Court ruling that overturned a two-term limit.

Murray invested $360,000 of his own money in the race, compared to about $94,000 raised by Buchanan.
