she will eat Vote of not just Sid but also Asim and Rashmi..
She will be Threat to other Top3
She only has overlapping fan base with shukla and can only cut into his vote bank. In finale if shehnaaz is standing she is only a thread to shukla as rashmi and asim have individual vote banks. But there is definitely an overlap in sanas and shukla and to a lesser extent rashmi and asim.
Rashmi and Asims votebank have now started to overlap too i think. Sana will cut shukla and rashmi will cut into asim in finale.
