Dismiss it at your peril. Cameron campaigned heavily in LD seats in 2015 and we saw how that went. Political parties have a lot more data than even the pollsters, I dare say that they have some pretty smart people crunching the numbers and telling them where to concentrate their campaign. Anyone who think otherwise is imo rather naive.
All true, but the size of the Tory majority at this point comes down to one thing and one thing only in my view - how many young people get off their arses and vote. Because I don't think Corbyn has managed to shift many middle-class/elderly/rich votes in his direction.
He needs an electoral miracle at this point.
