If you think she can really be that careless, then why believe anything she has to say?
The relevant questions are, what are the accuracy rate? Was it intended as a specific remark, or to illustrate a larger point? Was it careless, reckless, a lie, a damn lie, or a statistic?
Jumping the gun like you just did is not the way to bolster your credibility anywhere except on DU.
