These emails were requested a long time ago under FOIA, mostly when everyone was thinking "who the hell is Sarah Palin?" and a lot of stuff about Troopergate was flying around.
So, the release of them now is not exactly related to the media focus on her. That focus is due to her unusual quasi-campaigning and undeclared status in a lacklustre Republican field.
Naturally, I'd prefer if there wasn't so much attention paid to her without good reason, but a man can dream
The fact that 20-odd thousand emails
are being released is newsworthy enough and will be covered, seeing as how she seeks and pretends to avoid the spotlight incessantly.
