There are many ways to gauge whether Mississippi Gov. Haley Barbour (R) is running for president: you can track his movement in the early states, look at his personnel moves or listen to his speeches.
But there may yet be a more accurate way to predict his future.
Barbour, looking noticeably slimmer, recently told the New York Times' Jeff Zeleny, "I lost 20 pounds, and it made my back hurt" and "I have to lose about 20 more -- by the end of April." Others have also recently noticed the governor's weight loss.
"If you see I lose 40 pounds, you'll know I'm either running or got cancer," Barbour told reporters a little over a year ago.
As May grows near, keep an eye on the calendar -- and on Barbour's waistline.
