Will Congress and the media treat GM CEO Mary Barra any differently because she is a woman? Will there be cries of “sexism” if male lawmakers ask tough questions? At this time, Ms. Barra appears to be taking responsibility for GM’s shortcomings, even those that occurred before she took over on January 14. I seriously doubt that she will make any outrageous statements such as “What difference does it make?” The person who made that statement — about Benghazi — wants to be the next President of the United States. Whenever Mrs. Clinton is asked tough questions, her sycophants cry “sexism.” Politics is a tough business. So is running a business like GM.
