Will the Tribals vote for BJP in 2019?

If vote share in tribal belts of Chhattisgarh in 2013 Assembly and 2014 LS polls is compared with their performance in 2018 Assembly, BJP’s vote share went down while Cong's improved. If 2018 polls are compared with 2013 and 2014 polls, there is swing in favour of Cong and vote swing away from BJP.
