According to Mitchell, the comment was unscripted.
Off the cuff, spontaneous remarks are the best way to know what and how a person thinks.
HC has not said anything unscripted since her baking cookies remark. She isn't that stupid. Her remarks were intentional and scripted. She probably even had a poll done beforehand to test the reaction. She knew, of course, that the left/msm/Dems would cover anything she said.
Let's hope Hillary has a lot of time for unscripted off the cuff remarks--especially those delivered in her inimitable screech. They are golden.
