National Approval Ratings: In space of a month, BJP's West Bengal seat share projection drops by 7, as Mamata's TMC gains big

Even in 2014 Lok Sabha elections, when BJP-led NDA alliance reduced long-ruling Congress to its lowest ever Lok Sabha representation, state of West Bengal remained a step too far, as Trinamool Congress, led by WB chief minister Mamata Banerjee secured 34 of state's 42 seats. intervening four-and-a-half years have seen BJP pulling out all stops to make a foothold in Banerjee's bastion, and Republic TV-CVoter National Approval Ratings for vember have projected extent to which party has been successful.

Here is National Approval Rating for West Bengal -- essentially, who would win if elections were held in vember:

As is clear, NDA is projected to have gained a fairly substantial number of seats (9 in total) in comparison to 2 seats it won in 2014 Lok Sabha elections, even though, in essence, with a 32-seats projection TMC is projected to retain a similar seat share as 34 in previous elections. 

Congress, meanwhile, is projected to lose 3 of 4 seats it won in 2014, leaving it with a seat-share of only 1, while CPI(M), a tritional power in West Bengal, is projected to be wiped out, with a seat share of 0 compared to two seats in 2014.

In vote share terms, BJP is projected to gain from 16.9% (2014) to 31.5%, while TMC will also gain from 39.8% (2014) to 41.2%. CPI(M) is projected to lose heavily in terms of vote-share, from 29.6% in 2014 to 14.5%. Congress is projected to have seen its vote-share decline from 9.7% (2014) to 7.8%.

In comparison to National Approval Ratings for October:

Remarkably, BJP was in a far stronger position just a month ago in previous National Approval Rating where it was projected to secure 16 seats versus 7 in vember. TMC is projected to have gained 7 seats in process, while for Congress and CPI(M), it's status-quo.
