The two states are undergoing polls to elect their legislative members.
Mizoram, one of the four states where the Congress is in power at present besides Punjab and the union territory of Puducherry and part of a coalition in Karnataka, is the last remaining bastion for Congress in the northeast.
Apart from Modi`s appeal, the BJP is banking on the image of Chief Minister Shivraj Singh Chouhan and its organisational structure. Party President Amit Shah, Uttar Pradesh Chief Minister Yogi Adityanath and union ministers Rajnath Singh, Sushma Swaraj and Arun Jaitley campaigned in the state.
In Madhya Pradesh, the contest is mainly between the BJP and Congress through the Bahujan Samaj Party and Samajwadi Party are also in the fray.
