In Karnataka, the election battle is not just between Congress and the BJP but it is actually the battle between the incumbent CM Siddaramaiah and Prime Minister Narendra Modi. While Modi & Amit Shah are desperately making attempts to win Karnataka with the support of JD (S) and wants to unfurl the Saffron flag in South India, Congress wants to regain their hold on Karnataka and thus wants to show the nation that Congress still is a chief contender and has chances to bounce back to counter the BJP.
Although the likes of Rahul Gandhi, Sonia Gandhi and several other senior leaders of Congress are making a beeline to the campaign, and at the same time, many seniors from BJP such as UP CM Yogi Adityanath, Amit Shah are rallying, the real fight is between Siddaramaiah and Narendra Modi.
This is a clear fight between two popular leaders. If BJP loses Karnataka, not only it loses chances of winning any seats in South, it does have a telling effect in the North in the 2019 Lok Sabha polls. Congress too took it very prestigiously and leaving no leaf unturned to bag Karnataka in order to give a strong message to nation that is going to give tough fight to BJP in 2019.
All these boiled down to the battle between Siddhu and NaMo.
