Here's a look at the first phase of Gujarat elections 2017 through numbers

Gujarat goes to polls on Saturday, with more than 2 crore eligible voters expected to decide the fate of 977 candidates in fray for 89 seats in the first phase of the state assembly elections, widely seen as a barometer of Prime Minister Narendra Modi's popularity and a litmus test for the leadership of soon-to-be Congress chief Rahul Gandhi.

Factors at play
Anti-incumbency
BJP has to tackle a natural element of ANTI-INCUMBENCY that builds up after a long stint.

Discourse on development
BJP's 22-year track record. Does the development slogan still work?

CM face
BJP's best face is PM, but not CM any longer; absence of CM face for Congress.

Caste alliances
Rise of a section of the Patidars led by Hardik Patel; support lent to Congress by Alpesh Thakor (OBC) and Jignesh Mewani (Dalit).

GST
A negative perception about demonetisation and GST against the ruling party.

Controversies
Political discourse and controversies over remarks made by leaders such as Mani Shankar Aiyar.
