I don’t apologize for posting his entire post here, because if you want the links to every theory, you have to go over there. Mickey Writes:

I can see 5 6 7 8 9 10 Palin theories … and counting: 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. Gives you ulcers. … These theories are not necessarily mutually exclusive. … I have no fish in this hunt. … Update: Mediaite has intravenous drip. … see also HuffPo … Murphy is morphing! …
P.S.: Kurtz is sure! “No way Palin can run for president now.” …Update: Now he asks, “How can these talking heads pop off about the meaning of Palin’s resignation when not one of them saw it coming?” … It’s the return of Kurtz vs. Kurtz! … 4:35 P.M.
