Stephen Harper has in past acknowledged that keeping his weight down is a struggle. Shortly after his election in 2006, the PM confided to a Quebec TV host that the battle of the bulge has been the “problem of my life.” Harper shed a few pounds prior to the last election campaign, but he appears to have packed them back on in recent weeks. At his past few public appearances, the PM has looked noticeably heavier than he did late last year. Of course, standing next to the considerably leaner Barack Obama this week was bound to be unflattering to Harper. Still, it’s probably a good thing he skipped Obama’s trek to the ByWard Market for a sickly-sweet, deep-fried Beaver Tail.
