She has declined an invitation to keynote CPAC due to scheduling conflicts:
CPAC organizers invited Palin to deliver the closing-night keynote speech on Saturday Feb. 12, immediately following the announcement of the results of CPAC’s annual presidential straw poll, but after several days of negotiations, she declined.
“We’re disappointed that she wasn’t able to make it this year,” American Conservative Union Chairman David Keene said through a spokesman on Thursday. He noted that Palin “expressed interest in wanting to come this year,” but said that it came down to “a scheduling issue
While Palin will not be there in person, her political action committee, SarahPAC, is sponsoring a Diamond Reception on the CPAC’s opening night — Thursday, Feb. 10….
Had Palin accepted the invitation, she would have followed in the footsteps of Fox News host Glenn Beck who delivered the closing-night keynote address last year, and conservative talk radio icon Rush Limbaugh, who got the coveted slot in 2009.
I think the last paragraph is key. Had she accepted the invitation to give the keynote address, the narrative would have been that she’s following in the footsteps of Glenn Beck and Rush Limbaugh rather than pursuing higher office. Perhaps scheduling conflicts prevented her from speaking at any time prior to the keynote address on Saturday (her birthday occurs during this period as well) and that she didn’t want to get pigeonholed as another Rush/Beck by delivering the closing address. Her PAC will sponsor another event at CPAC Thursday evening.
