BSP chief Mayawati on Tuesday said that her party lost in the Haryana polls due to the "casteist" mindset of the Jat community of the state. "Jat community of UP have changed their casteist mentality...Haryana should also follow their footsteps," she added. BSP fought Haryana polls in alliance with INLD. BSP didn't win any seat, while INLD won two seats.
