"We always said we will win the heartland states," BJP President Jagat Prakash Nadda told Reuters.
However, a 28-party opposition alliance led by the Congress party has come together to jointly fight BJP, posing a new challenge.
But the alliance did not feature in the state polls due to internal rivalries and it was a direct contest between BJP and Congress.
Politicians and analysts say state elections do not always influence the outcome of the general elections or accurately indicate national voter mood.
Results of the last round of state elections before national elections have been misleading in the past.
