until she says “I’m running” she isn’t
You mean like Fred Thompson said he was running but didn't?
Sarah Palin has been running ever since she resigned as governor.
(For those you still don't understand that decision, it wasn't because she was "forced" out. Palin outmaneuvered her enemies, which, btw, includes the GOP power brokers. Look at her activities since then, her speeches, writings, travel,endorsements, etc. She was a sitting duck in the governor's office, trapped on defense. Ever since, she has been on offense. She took on Obama when no one in the GOP had the guts to do so. Either people are forgetting that or they were clueless about what she's been doing because of their own prejudices about her.)
