Through the door-to-door campaign, the ruling party, which is yet to declare candidates for the upcoming elections, plans to reach out to voters under 50,000-odd booths in the state.
Mr Shah launched the campaign from the Naranpura constituency, from where he was an MLA earlier, after offering prayers at the Goddess Ambaji Temple in the Sola road area.
He visited around 10 residential societies, including Parasnagar, as part of the campaign.
Amid beating of drums, the Rajya Sabha member, along with a large number of BJP workers interacted with residents, went inside some houses, asked about their well-being and requested them to vote for the BJP in the coming elections.
The people were seen welcoming the BJP chief, who was their MLA since 1998 but had resigned from the post after being elected to the Rajya Sabha a few months back.
Amit Shah along with other party workers distributed copies of a letter written by Prime Minister Narendra Modi, to voters in every house where they campaigned.
Mr Rupani campaigned in Gandhigram area of his Rajkot-2 constituency, while Patel campaigned in her Gathlodia constituency of Ahmedabad city.
The party's senior leaders as well as booth-level workers interacted with voters under various booths across the state.
The exercise is aimed at telling people about what the BJP has done for the state's development.
The polling for the two-phase elections in the state will take place on December 9 and 14 and votes will be counted on December 18.
Several Union ministers - Smriti Irani, JP Nadda, Nirmala Sitharaman, VK Singh, Mansukh Mandaviya and Prakash Javadekar - would also visit Gujarat during the drive and interact with voters at their designated places, Gujarat BJP spokesperson IK Jadeja yesterday said.
