"...will this saga actually sway a significant number of votes?"

No.  Because, in the end, self-interest will trump (yeah, I know, I know...but think about it!) ethics and morality, even common decency (which is kind of a lowest common denominator, really) as Trump's successful campaign demonstrated beyond all doubt. 

Much MORE important than the Linda incident is the headline of the G&M story just a few days ago.  Here's the headline:  BC Liberals cite jobs as top election issue; NDP pledge climate action."

Now, if that headline was a front-page story in the Vancouver Sun, with big follow up on west coast CBC and CTV  it would have a HUGE impact.  But, because it was a Globe and Mail headline, not so much.  For which the BC NDP can be grateful, because, "climate action" looks pretty insubstantial next to "jobs."  Even looks  lame next to Gonna-cut-coal-to-show-those-Americans-something! 

Ok, Rich, put up or shut up.  Will the Linda incident sway MY vote?  'fraid not.
