For the polls to be cooked you would need the active participation of literally hundreds of different polling companies, coupled with none of the employees of those pollsters deciding to reveal the vast left-wing conspiracy. I don't think most of those complaining about the polls have any idea just how hard polling is to get right, even if you're being completely honest. There is a shit load of educated guesswork in the turnout modeling and the demographic adjustments, and that the polls get as close add they do is a minor miracle. Go and read the British Polling Council postmortem of the 2015 General Election failings if you want to look at the gory details: it's really quite transparent. Not to say there aren't careless and partisan pollsters in the world: there are lots of both. But there's no need for conspiracy theories when the reality looks like this.
