Why won't Sarah Palin answer any questions??

From the Associated Press (certainly NO liberal outlet) after the ABC interview later this week:

McCain campaign manager Rick Davis has said that Palin will "agree to an interview when we think it's time and when she feels comfortable doing it."
"She's not scared to answer questions," Davis said on "Fox News Sunday."

Doesn't this BOTHER anyone out there???? If she's not scared, why is the McCain campaign scared????? Exactly WHEN will they think it is TIME?
Since when can't a mother of five with SO MUCH EXECUTIVE EXPERIENCE answer some questions?
Sounds WAY too Stepford wife to me...
