This is what it says: The exit poll conducted by CNN-IBN and Indian Express newspaper projected BSP would end up with a seat share of 152 to 168 seats, followed by SP with 145 seats and BJP ending at the third spot at 108 seats.
The seat projection for Congress was put by this survey between 21 and 27.
Add up the numbers and the total is 430... how can there be 430 winners in 403 seats?
