There have been stories about Sarah Palin going to Iowa to steal the spotlight from actual candidates for the Republican nomination, but she, herself, has just been upstaged.
Sarah Palin said she was going to Iowa to eat junk food, but Texas governor Rick Perry is going to Iowa to campaign for the Republican nomination for President. It's probable that Perry is going to get more attention than Palin while they are both in Iowa, tomorrow.
How is Perry unlike Palin? He has completed two terms as Texas' governor, and, in his third term, he is now the longest serving governor of Texas. How many terms did Sarah Palin complete as Alaska's governor? In some other respects, they have much in common, so don't be surprised to see Palin endorse Perry.
An Austin, TX website has a story about Perry's announcement: "It's official, if familiar: Perry's in."
He (or she) who hesitates is lost.
