The ruling BJP in Haryana seems confident of winning the next Assembly elections on the basis of its performance and also because the most opposition parties in the state are in disarray.
While the main opposition the Indian National Lok Dal (INLD) has been reduced to a minority as most of its legislators and leaders have joined the BJP, infighting continues to dog the Congress, which ruled the state for two consecutive terms till 2014.
The Congress this week appointed Kumari Selja as the new state unit chief replacing Ashok Tanwar, while making former Chief Minister Bhupinder Singh Hooda Chairman of the Election Committee.
Khattar's slogan 'Mission 75' has got louder after the party's stellar performance in the last Lok Sabha elections, where the BJP won all the 10 seats a first in state's electoral history.
He is the first BJP Chief Minister of the state, which was formed on November 1, 1966, and aims at improving the party's tally in the Assembly from 48 legislators.
