During Mapes' CNN-Blitzer appearance, she appeared to be under the influence of alcohol or drugs. IMO.
This rebuttal by Emily Will is devastating to Mapes, but Mapes seems oblivious to any criticism.
I have come to understand that to an MSM "reporter" the phrase, "I stand by my story", is meant to clinch the argument. After that we mere mortals are meant to defer to their superior judgement.
