Rane's elder son Nilesh had lost the Lok Sabha election from Konkan's Ratnagiri-Sindhudurg seat in May this year and his close associates Ganpat Kadam, Subhash Bane, Rajan Teli and Ravindra Phatak have all deserted him to join Sena or BJP.
Differences with Rane have led former Minister of State for Urban Development and NCP legislator Uday Samant into Shiv Sena, who is their candidate from Ratnagiri seat.
Rane's younger son Nitesh, who runs NGO Swabhiman and is not a primary member of the Congress, is contesting from Kankavli, which has caused some huffiness among local Congress workers, but there is no open protest against his nomination.
Observers here admit that the prestige of Rane, who is Congress' campaign committee chief, is at stake in the polls.
"Though both father and son may scrape through, the multi-cornered contest makes the poll results anybody's guess," they say.
"People in Kudal have got confidence that Rane can be defeated. In 2014 Lok Sabha polls, Shiv Sena got a lead of 22,000 votes in Kudal Assembly segment," Naik said.
Several of Rane's supporters have deserted him. People also know that Rane's resignation from the government few months back and withdrawing it was "due to his selfish personal motives and not development of Sindhudurg," he alleged.
"My campaign is to tell people that despite being the guardian minister of the district, Rane had failed to develop Sindhudurg. He has not got a single project to the district to improve employment opportunities for the youth," he said.
Shiv Sena giving a ticket to Subhash Mayekar, former NCP leader, has not gone down well with staunch Sena supporters.
