1) Your post did not refer to Trump or the US but the to the shy Tory factor in the UK, which I repeat has long been laid to rest as an issue (including on U75).Where has it been shown to be wrong "time and time again" in the USA with Trump? I'm waiting for the reference I asked for. I just said it happened once, which you agreed with although I got the date wrong.
2) Nearly all modern polls wherever they are in the world weigh by a wide variety of factors,
3) National polling for the US elections was very good in 2016, and has been good in general for some time. There was little to no evidence of any shy Trump voters in 2016. If people are going to seriously propose that there is a significant body of shy Trump voters in 2020 then fine but let's have some proper evidence.
