I called Gander, who owns Rochester's Superior Mechanical. When asked about the rumor, he said "I am not prepared to make that announcement today."
When I pressed him on whether or not he was running, he said, "I don't think you deserve to know before the delegates deserve to know."
I did follow up and ask if he would make the announcement at tonight's endorsing convention, and he said if the rumor is true that "would be a good assumption."
Gander has been busy campaigning to run against 1st term DFL Sen. Ann Lynch of Rochester. He embraced a construction theme as part of his campaign with the slogan "Jim Works." Here is his Web site.
Republican Party of Olmsted County Co-chair Bruce Kaskubar said he could not comment on the rumor.
The endorsing convention begins at 7 p.m. at the Heintz Center at Rochester Community and Technical College.
