In this case, it’s the fact that Sarah Palin has declared that she will not run for President in 2012, which means that I can add her to my list of They Who Must Not Be Named:

Sarah Palin said she won’t seek the 2012 Republican presidential nomination, ending a lengthy and attention-grabbing political flirtation that kept voters and potential rivals guessing while buttressing her public profile.

The former Alaska governor and her party’s 2008 vice presidential nominee — more recently a reality TV star and cable-news commentator — said she opted against a White House run because she believed “that at this time I can be more effective in a decisive role to help elect other true public servants to office — from the nation’s governors, to congressional seats and the presidency.”

Her announcement, in a statement sent to supporters today, removed a major uncertainty surrounding the Republican presidential race while raising questions about how she might use her celebrity and political following to shape the primary.

“I will continue driving the discussion for freedom and free markets, including in the race for president,” Palin’s statement said.

“I will help coordinate strategies to assist in replacing” President Barack Obama, keeping Republican control of the U.S. House and helping her party win a Senate majority, she said.

This means that I never have to write about her, or read about her, again.

While we are at it, let me add the following people to my list:

• John and Kate Gosslin.
• The cast of The Jersey Shore.
• The “Real Housewives” of anywhere.
• Nancy Grace.  (If she flips out on national TV, or is tried for a crime, this is suspended for reasons of schadenfreude)

Actually, let’s say that it includes pretty much any reality TV star.

In any case, Sarah is now done.  She’s made her bucks off of her 15 minutes of fame, and she was a springboard for Michelle Bachmann to become a viable (?) presidential candidate.  (The Republican Crazy Bitch Babe is the genre that she created.)
