While Sinha said he has not received any invitation to the programme, MP Ashwani Choubey, former state minister during the NDA rule, was not allowed to sit on the stage.
"Neither party president Amit Shah nor the BJP state leadership invited me to the function," Sinha, BJP second term Lok Sabha member from Patna Saheb, told PTI.
"My name or photograph does not figure in any of the banners, hoardings and posters despite being a city MP," he said over phone from his Mumbai residence.
Asked if BJP would win the Assembly polls without him, the party's star campaigner for long wished them luck.

On the absence of Sinha's name in posters, senior party leader Sushil Kumar Modi said those were put up by individuals and not by the party.
Choubey went to the programme but security personnel did not allow him to go inside protected area in his car as his name did not figure in the list of persons to be seated on the dais.
Senior Superintendent of Police of Patna Jitendra Rana told PTI that security personnel had no role in deciding about who would sit on dais which is done by the organisers.
Besides Shah and Rajnath Singh, BJP general secretary Ram Lal, BJP Bihar in-charge Bhupendra Yadav, union ministers Ravi Shankar Prasad, Radhamohan Singh, Rajiv Pratap Rudy, Dharmendra Pradhan, Giriraj Singh, Ramkripal Yadav, Syed Shahnawaz Hussain and C P Thakur were on the dais.
State leaders like Sushil Kumar Modi, Nand Kishore Yadav, state party president Mangal Pandey and all former BJP ministers in NDA government in the state were also on the stage.
Chief Minister Nitish Kumar took a swipe at BJP on this. "How come a party, which cannot take care of its own leaders, take care of the masses," he said.
