Leger Quebec poll: 39/21/21/8/6. Grit gains, Dipper shutout and Bernier threatening to split the Quebec City vote.
Which makes me thinking that Beauce, for example, could be winnable for the LPC.
If you get a perfect split, absolutely, although I think Bernier's popularity is overrated in Beauce. His riding has a large dairy farming industry so it will be interesting how his stance on supply management goes over, but certainly possible.
He lost his own riding during the leadership ballot, if I recall correctly.
EDIT: Correction/Clarification - I've checked the Wikipedia maps, he led on the first ballot in his riding, however Scheer won a majority of his riding on the final ballot.
