Her own claim about herself, not mine.
Back in 1996, Wendy Davis lost an election for the Fort Worth, TX City Council. After the election, she sued the Fort Worth Star-Telegram, the local newspaper, for defamation. In short, Davis did not like being criticized by the media (something she won’t have to worry about this go round), so she sued for those criticisms claiming they defamed her.
The Texas Court of Appeals and then the Texas Supreme Court both threw out her case. But it is worth noting that Davis, in making her case, claimed that the nasty newspaper, by virtue of criticizing her, damaged her “mental health.”
More worrisome regarding her mental stability, Davis sued the newspaper months after losing her city council and claimed that she “ha[d] suffered and [was] continuing to suffer damages to her mental health.”
Seems to me that Wendy Davis is too unstable mentally and emotionally to be governor -- after all, she clearly can't stand the heat of a tough political race or criticism of her positions.
Of course, I suppose the media could treat her like they have Obama for most of his career in office.
