Clay County Democrat Party Vice Chair Guy Dickerson was very sorry to hear of Linda Moreau's resignation as party chair.
"I was shocked, but I knew Linda hadn't been feeling well," he said Friday, describing her as an "energetic, fast-paced person."
"We're going to have a hard time getting someone as dynamic as she was in the job."
Moreau resigned Thursday night on orders from her cardiologist.
Moreau had heart surgery last fall and had been feeling stress lately.
Dickerson said Moreau's tenure as party chair was marked by "big strides in getting the party out in front of the public again."
Moreau said Friday she was sad to announce her decision.
"My heart is broken," she told The Times. "My heart is so heavy. I just loved (being chairperson).
"You have to set priorities and my family comes first this time."
Moreau lives in Center Point with her husband, Don. Her children include Clay County Auditor Joe Dierdorf.
Dickerson's next job will be to notify Indiana Democratic Party Chair Joe Hogsett of Moreau's departure. Hogsett will then call a Democratic Party caucus in Clay County within 30 days to select a new county party head.
At that caucus, nominations will be taken from the floor, Dickerson said.
