regd the bengal situation,
i had this fortune of being able to converse with lots of (at least 25-some) bengalis on teligram when that last legislative assembly election was happening, and through them i got some pointers regarding their election things
> Mr. Modi could easily have won there, because there was anti-incumbency against Ms. Banerjee - BUT the party spoiled their winning game on their own by doing some stupidities like,
-> going full gear on muh 'subaltern hindutwa'

, meaning non-bhadralok bengalis are true hindutwa guys hurr durr chhap propaganda, both on social media as well as in street prachaar - this irked the considerate numbers of bhadralok hindu bengalis who may have voted for BJP that time

-> going full gear on muh 'pashmanda musalman' sochit vanchit hurr durr

- jo inke voters hi nahi hai unko patane jaate hai, baar baar har election me laat padati hai toh bhi, Mr. Modi himself going bear-hugging certain kanglu looking pashmanda there for photo-ops during very critical stage of the elections just ruined it for them
^overall here^ - going full ambedkarwaadi in front of people who aren't even much into such ambedkari things (though it's another fact that without support of bengali like Joginder Nath Mandal and Muslim League there, Mr. Ambedkar could never have reached to the Constitutional Assembly during '47 times, but irrelevant here)
-> GOING FULL GEAR ON "DIDI, O DIDI!" CHHAP DIRECT TAUNTS TOWARDS Ms. BANERJEE

- a hell of voters there, 'specially the bhadraloks took it as quite crass thing and turned their heads away
-> GOING FULL GEAR ON SIDELINING LOCAL LEADERS LIKE SUVENDU ADHIKARI,
DILIP GHOSH BABU AND SO, WHILE GIVING IT TO MR. SHAH TO RUN THE ELECTION THINGS THERE

- simply didn't play out well, because even Mr. Shah was going out talking about how their government has brough 'teen talak ka kanoon' to public who have little to no understanding or even care about these things!
but all things said, BIGGEST REASON OF BJP LOOSING THAT ELECTION, WAS
NOT GOING FULL GUNDAA MODE THERE - a bengali friend of mine on teligram himself worded it in this words, that "hamko aisa leader chahiye jo street power ko street power se kaat sake, aur hamko hausla de ki hamare logo ko election ke pehle-dauran-baad me protect kara jaega...iski jagah BJP ke log toh khud bhaag gye jab chunavi himsa hoti hai, unke khud ke karyakarta ko pedo se latka kar maar rhe hai aur yeh log bas bayanbaazi naarebaaji karte hai - aise NAPUNSAKO ko bengal me kabhi jeet nahi milegi, kyounki idhar chunav baad me jeete jaate hai, pehle streets jeeti jaati hai"
yeah yeah muh CRPF and armed units deployed by centre was there, but everyone had been warned by goondas that 'they're here only till elections, unke jaane ke baad tumko kaun bachaega'

- and personally speaking, i can't disagree with his comment...LIKE EVEN WEST BENGAL HIGH COURT HONOURABLES THEMSELVES WERE CRITICISING BJP FOR NOT APPEARING IN FRONT OF THEM FOR MAKING UP A CASE ON POST-POLL VIOLENCE!

, THEN MR. NADDA THE PARTY PRESIDENT WAS LITERALLY DOING
ONLINE DHARANA AGAINST POST POLL VIOLENCE
oh btw, this friend of mine whose statements i quoted (based on my memory of course) himself fled to nearby state jharkhand to some uncle's place when elections concluded there as he was on aim of certain party's goons for his activities, a lot of people fled to bihar-jharkhand-orissa side to save themselves
overall, wanna win bengal ? GROW BALLS BIGGER THAN THAT TIGRESS BANO AND OWN THE STREETS FIRST!
