It isn't a hard shift to the right - those voters were just effectively disenfranchised by Christie Clark pushing BC Cons out of the realm of possibility by being so far right. They're the absolutely brain dead idiots that refused to vote for Clark because "She's uh libruhl" while she ran an extremely right wing political agenda.

The actual incomprehensible event was that she was ever able to capture that position in the first place. It was before my time but I'm amazed she ever managed to capture BC Liberal voters with her far right platform in the first place.

BTW, when I say BC Cons voters are absolutely brain dead I mean it. The huge number of voters that suddenly appeared are super low information party loyal folks.
