The battle has begun. Prime Minister Narendra Modi launched his Lok Sabha campaign with a rally in UP's Meerut, marking the first of a staggering 150 rallies and roadshows he will hold over the next 51 days. Rahul and Priyanka Gandhi have some 100 rallies planned in about the same amount of time. Tonight, we look at how PM Modi's campaign in 2019 is different from his campaign in 2014. 2014 was all about the Modi wave, five years later, there isn't a wave anymore, but does he still have the edge? Is PM Modi unbeatable or is this race wide open?
