I once asked my driver in Kolkata, who's a hardcore TMC supporter, why support didn't go to the BJP. He told me that most of the BJP supporters are ex CPM supporters, that's why, and people remember the LF's misdeeds
Essentially, Bengal will have to wait 2 generations, if not more, before they can have a sensible electorate. That's assuming that the state hasn't become Kashmir by then
