Recent polls suggest a relatively narrow gap between CPC and LPC for female support (e.g. 36% LPC 33% CPC per Campaign Research poll in Feb 2017).  Sure, the LPC depends on a significant base of urban female voters, but I'd hardly suggest a sweeping generalization that CPC only cares about male support.   I'd argue Trudeau is taking feminism too far and that a more neutral approach by Scheer is not going to hurt his campaign, possibly the opposite.

This won't likely be a wedge issue in 2019; more likely deficits and taxation.
