Here's a minor point, doubtless far from specific to the BBC...but, as the BBC provided such a clear example of it, here goes nothing....
Tuesday night's Newsnight saw newly-imported Newsnight "U.S. correspondent" Emily Maitlis talkin' Trump in Tennessee.
Our Em - before the Super Tuesday results came in - affirmed (as per the polls) that Hillary was likely to sweep everywhere except Vermont and that Donald Trump would sweep 10 out of 11 states - and I believed her.
Alas for the pollsters, their media followers (including Newsnight) and us overly trusting Newsnight viewers, it didn't turn out like that: Bernie Sanders beat Hillary in four states and Donald Trump 'only' took 7 out of 11 states.
So much erroneous speculation based on polls....
Do they never learn?
