Mickey Kaus counts 10 theories about Sarah Palin.

I thought it was obvious that there was only one, but Mickey has all these:

1) She's running for president; 2) She's undergoing fame withdrawal and plans to get more attention in the lower 48; 3) She wants to cash in ($); 4) There's another shoe about to drop; 5) She'll now run against Murkowski for Senate. 6) She needs to tend to her family. 7) She's bonkers. 8) She's preggers. 9) She wants to "effect positive change outside government at this point in time on another scale and actually make a difference for our priorities." 10) Actually being a governor in a recession is no fun.

Well, the obvious and only theory to me was #1. Mickey's #2 and #3 merge with my view of #1. Eh, so do they all really.
