Labour won by elections in Sheffield and Oldham this year with 62% of the vote in each - and increase of 6% and 7% so pre leadership election it seems you are right to think the North is more secure for Labour than Scotland.
they were safe sodding seats!
look at the historical precedent, the vote increases were less than under Miliband in comparable seats. add in the fact that oppositions almost always do well in by-elections, especially in safe seats, and it's hardly a sign we're on course to even keep all the seats we have
