"Modiji is bothered only about Modiji. PM Modi is only bothered about becoming the PM again. He isn't bothered about rapes," the Congress president said, addressing party leaders and workers at a huge indoor stadium in Delhi.
The Congress had worked for the country's prestige for 70 years but it was all undone by the BJP-led government, he said. PM Modi, he charged, had damaged India's image in the past four years.
"We will never allow the BJP and RSS to even touch our constitution. The people of India will speak their 'Mann ki Baat' in 2019."
The Congress will continue its nationwide campaign for nearly a year till April 14, 2019.
Rahul Gandhi liberally took potshots at PM Modi, using his comments.
BJP Chief Amit Shah took no time to hit back at the Congress president saying, "Our institutions which are an outcome of our Constitution today need to be saved from the onslaught of the Congress Party. The Congress Party has spared no institution and is attacking the EC, Supreme Court, Army for petty political gains."
"By repeatedly saying the Congress made the Constitution, Rahul Gandhi is carrying forward his family tradition of insulting Dr. (BR) Ambedkar. The Nehru-Gandhi family insulted him when he was alive and his humiliating him even more now. Shameful and petty," Mr Shah said.
The Congress campaign comes at a time when the ruling Bharatiya Janata Party is holding "Gram Swaraj Abhiyan" across the country under which PM Modi has asked party lawmakers to spend a night in Dalit-dominated villages.
The Prime Minister's direction to party leaders came after violent protests erupted in parts of the country after a Supreme Court order allegedly diluted the Scheduled Castes and Schedules Tribes (Prevention of Atrocities) Act.
