I understand “why” Ann doesn’t like Newt.

She supports Mitt simply because he’s the “best situated”, non-Newt candidate.
She can’t really defend Mitt’s record and it makes her mad that she is forced into that role.

Her level of anger makes it clear that Mitt is losing the battle and she can’t stand the thought of having to support Newt or accept Obama.
