There is no point in saying, what will happen in 2019. Still a long way away. The bottom line is none of the parties have a game plan. BJP was supposed to lose UP. AAP was supposed to romp home in Punjab. AAP was supposed to get seats in Goa. Congress was supposed to form governments in Goa, Punjab and Manipur. What happened?
Zilch. Unless a proper strategy is made out on how to tackle the current government with issues instead of simply going anti-Modi, its going to be UP all over again. And, they need somebody besides Pappu. Even Congressmen in private, mention on how they are supposed to win elections if he cannot keep his trap shut.
Fence sitters will make a big difference in 2019. A 3% change in voteshare will be the difference between 300 seats and 100 seats.
