All models for the 2017 GE were rendered moot by the campaign, probably the first in my lifetime to significantly change the outcome of an election.
Loss of a by-election weeks before, disastrous local elections, record approval for PM May and 20% poll leads all presaged meltdown for Labour, but PM May threw it all away in the space of a couple of weeks, as Corbyn radiated authenticity, good humour and a "new kind of politics."
I actually noted in emails to my circle that the early June Ipsos/MORI Political Monitor poll revealed an unprecedented and catastrophic falling away in approval of Theresa May. I further noted that when applying these numbers to the Lebo & Norpoth PM approval model (a second-order autoregressive equation found in the expert paper) the central forecast outcome would be a Hung Parliament. Matt Lebo had made his final prediction of a Tory landslide, based on earlier highly-positive MORI polls for PM May, and I don't think ever updated his final prediction with the extraordinary final poll. I never came to a firm view, but kept my options open until the exit poll, when I made a couple of £k.
Re Trump. I tipped him in Feb 2016 to win, five days before Professor Norpoth did the same based on his Primary Model. I stuck to my prediction throughout and in September said the pollsters and pundits would be "eating the biggest banquet of crow since 1948." In the event I won £40k on President Trump...
