Liz Cheney was a carpetbagger. Scott Brown would be a carpetbagger. What difference does it make who they’re taking on? The stigma is stil the same.
A carpetbagger is an outsider who wins a rigged game.
Hillary was a carpetbagger in NY but would not be a carpetbagger in Texas.
Cheney thought she had a rigged game where she could use her name recognition and national fund raising and pummel Enzi in a primary where very few vote and then pummel the democrat.
Brown is in a very competive race where the game is not rigged.
Also the states in NE are so small, Brown grew up about 40 miles from the NH border.
