It all makes perfect sense – the campaign would revolve around highlighting their gubernatorial accomplishments.

Sarah Palin (r) on July 3, 2009:

Palin Announces No Second Term

No Lame Duck Session Either

…And we are doing well! My administration’s accomplishments speak for themselves. We work tirelessly for Alaskans…

…With this announcement that I am not seeking re-election… I’ve determined it’s best to transfer the authority of governor to Lieutenant Governor Parnell; and I am willing to do so, so that this administration – with its positive agenda, its accomplishments, and its successful road to an incredible future – can continue without interruption and with great administrative and legislative success…

Matt Blunt (r) on January 22, 2008:

Gov. Matt Blunt won’t run for re-election

…”The habit of politicians is to remain in office, and the desire to prove oneself in the next election is strong,” Blunt said. “After a great deal of thought and prayer, and with the knowledge that we have achieved virtually everything I set out to accomplish, and more, I will not seek a second term in the upcoming election,” he said.

“Because I feel we have changed what I wanted to change in the first term, there is not the same sense of mission for a second…”

And their administration could include South Carolina Governor Mark Sanford (r) as Secretary of State. After all, it’s the international experience that counts.
