In a statement, the Bharatiya Janata Party (BJP) said the two senior leaders will talk to both ruling NDA and opposition UPA constituents, besides other political parties as well as independent members.
They will soon begin holding these consultations, the party said.
Opposition parties had accused the BJP during the last presidential polls in 2017 of reaching out to them at the last moment, after it had already finalised the choice of Ram Nath Kovind, who went on the become the president.
The opposition had forced a contest by backing Meira Kumar, who lost to Kovind.
The presidential polls will be held on July 18.
