You have to admit, Sarah Palin’s very good at one thing: quitting.

Sarah Palin’s Saturday appearance at a tea party rally in Indianola, Iowa, is on hold, a person close to the former Alaska governor told The Wall Street Journal.

The person said Ms. Palin’s appearance was “no longer confirmed” and cited “continual lying” from event organizers at Tea Party of America, including a recent mixup over whether former U.S. Senate candidate Christine O’Donnell of Delaware would also speak.

Ms. Palin is known for last-minute schedule changes that whipsaw supporters and media across the country. But the latest decision is puzzling. Ms. Palin’s speech at the rally was viewed as her most high-profile appearance of the summer, fueling  speculation she was indeed plotting to run for the Republican presidential nomination.
