The exit polls have a history of underplaying the United Progressive Alliance (UPA), while it has historically overplayed the National Democratic Alliance’s (NDA) performance.
In 2004, the average of the exit polls had predicted 252 seats for the then incumbent NDA, giving it yet another term at the center, and 186 seats for the UPA.
