My reasonable point about her has always been that she seemed way over her head in any discussion of world affairs.
That she didn't seem particularly bright, nor even all that well coached -- which admittedly is close enough for most politicians, considering how well the talking heads stay on-script.
That she had no visible points to make other than attacks, soundbites, style-over-substance, and folksiness.
That every accomplishment she tried to claim in her tenure as mayor or governor turned out to be much less than what she claimed, or in fact completely opposite what she claimed.
And finally, though this is not technically her flaw, the fact that every defense of her seems to come down to one of two things: You're afraid of her, because she's a strong woman who is also a conservative. Or ... Some Democratic politicians have similar flaws.
By the way, what "rape rack and ruin" are you talking about?
