Political strategist-turned-activist Prashant Kishor on Saturday exuded confidence in his soon-to-be political party Jan Suraaj. Addressing a public event, he said, "Earlier I had worked for (West Bengal Chief Minister) Mamata Banerjee, (Tamil Nadu Chief Minister) MK Stalin, (Delhi Chief Minister) Arvind Kejriwal, and (Bihar Chief Minister) Nitish Kumar and I made them win. So now that I'm working for Jan Suraaj, I won't let the party fail."
