I feel like one reason she has had such popular success is she gives voice to a chronically underrepresented group: Conservative (heartland especially) women. This is no small minority, and in the past there have been few women in the spotlight of politics who could capture that voice, and she really has.
It disheartens me when people on the left dismiss her so roundly. Also the worn out "STUPID!" saw has gotten very old since it is used almost universally about folks on the right. Likewise the same sort of droning sound that comes from the right about it's opponents is annoying.
THAT is the tone I want to see go away, if there is one.
