I think she finds that playing IW, then skipping Miami, givers her a chance to spend an extra two weeks at home with her Mom, and now her husband. She's real close with her Mom, and her husband doesn't travel with her, so that's a good time for a break, since the tour has just returned from Europe and Africa (or if you prefer, the 'Middle East').
The only real downside is that Davenport is the task facilitator on the women's tour. If she doesn't play Miami, the whole idea of mandatory tournaments goes out the window. Davenport isn't a maverick. If she does something, that's damn nnear the 'Good Housekeeping Seal of Approval'.
Proud to be an American
Not blind. Not uninformed. We are party to atrocities. But the response of the world after 9/11 is worth noting. Even our most dire enemies offered aid. We should all be so lucky.
