David Stoltzfus says there’s only one reason he would take down the photos of President George W. Bush that he has displayed at his Central Market baked-goods stand. Bush would have had to have lost the recent election. Instead, he beat Democratic challenger John Kerry to win a second term. “If it were Kerry that won, he’d be up there,’’ says Stoltzfus, who operates the Upper Crust stand. Doesn’t matter, says City Councilman Nelson Polite. “It should come down. This is a public market.”
