"There’s just too many people running," Thompson said. "Any time someone jumps in, they cut your percentages down."
Thompson said last week he was considering ending his bid. He had said he had launched his campaign earlier in the year assuming he would be in a three-way race with former ambassador Tom Schieffer and humorist Kinky Friedman.
There are now at least four Democrat candidates for governor -- Schieffer, Friedman, East Texas rancher Hank Gilbert and Fort Worth teacher Felix Alvarado. Houston Hair-care magnate Farouk Shami and former Travis County District Attorney Ronnie Earle have said they may join the race as well. Candidates can not officially file for a place on the March primary ballot until December.
Thompson said he is endorsing Gilbert, who most closely matches him on several key issues including an opposition to toll roads.
