Tonight was one of them: the BJP election machine, stunned in Karnataka, where the somewhat rickety JDS-Congress alliance managed to win four out five seats in crucial by-elections. This included the Ballari seat held unbroken by the BJP for the past 14 years. Is this an isolated win, based on local factors, as the BJP claims? Or does this hold signs for 2019? To answer that, we spoke to man of the match HD Kumaraswamy, who now has his eyes on all 28 Lok Sabha seats in the state in 2019.
