Significance about the Assembly Segments:

While two of the assembly segments belong to the Panchkula district, and three segments cover the Yamunanagar district, the remaining four assembly constituencies cover the entire district of Ambala.

 About Ambala:

While Ambala city is the administrative headquarters of the Ambala district, Panchkula city is the administrative capital of the Panchkula district. Though the region of this Lok Sabha constituency is primarily a rich agricultural region, the three districts of Ambala, Panchkula and Yamunanagar have some small scale industries, which are the primary strengths of the economy.

Demography:

The district of Ambala houses a population of 11,28,359 people, as per the 2011 Census.

 Present Political Scenario:

 Congress losing ground
The very fact that Kumari Selja opted out of this seat tells the story of how badly the Congress is placed here, which has also apparently demoralized many grass-root workers of the party.

 May turn out to be a BJP Versus BSP contest
BJP has nominated former MP, Ratan Lal Kahariya, who had won this seat in 1999 and had lost in 2009 (to Selja) by a very low margin of less than 2%. It is believed by many observers that this time Congress maybe out of contest from here at least in 3-4 assembly segments where the fight would be between BJP and BSP.
