Republicans, who mock Barack Obama as a self-appointed divine savior, gleefully pounced Thursday on pictures of the set for his big convention speech, which appears to resemble a temple. The Democratic presidential candidate will accept the party White House banner before a more than 70,000-strong crowd at an outdoor football stadium here late Thursday. Pictures and an aerial film footage of the set being constructed for the speech show a curved backdrop with creamy, gray column-like structures, which could suggest Washington architecture, or a classical structure, like a Greek or Roman temple.
