As we've discussed in the past Trump was often his own worst enemy, allowing his missteps to overshadow ones by Clinton.
We'll see if that message discipline continues.
@dandydan as I understand it there are some quirks to both British and US polling that make them somewhat different animals. I don't follow UK polling so haven't got a feel for how accurate or not they are. However I've been following US polling for several years now though and am much more comfortable with the data although no poll will ever be 100% accurate.
But it is obviosuly up to an individual as to how much they trust it or if they they discount it completely.
