While those of us who dislike Trump are going to find Stefanik’s transformation into a hardcore Trumpist cringeworthy and shallow, it’s (unfortunately) not a bad electoral strategy in a district that is trending Republican and went pretty strongly Republican in 2016. Republicans seem to understand better than Democrats how important base turnout is these days, and that merely being “moderate” doesn’t woo hoards of swing voters.
I feel a distinction here is that while the Republican coalition is overwhelmingly conservative the Democratic one is a mix of liberals and moderates.
