WION's Political Editor Kartikeya Sharma quoted party insiders as saying Mayawati was opting out of the elections because she did not want to be tied down to one constituency but would instead like to concentrate on campaigning for the party. She is expected to campaign outside of her bastion of Uttar Pradesh.
Sharma added that Mayawati also wanted to keep open the option of contesting the 2022 assembly elections.
Having said that, there is also the fact that Mayawati has ceded at least some space to new Dalit leaders like the Bhim Army's Chandrashekhar Azad and Jignesh Mewani. And should her victory margins now be less than impressive, that will further bring down her stature.
