Boy, seems like everybody’s doing radio talk shows these days. The latest figure who might be hitting your airwaves? Rudy Giuliani.

The questions raised in the Page Six item seem pretty legitimate — one, most Republicans and New Yorkers would prefer to see Giuliani out giving some New York Democrat the race of his or her life, as either a gubernatorial candidate or a senatorial candidate. Second, while he’s an entertaining figure and a great storyteller, it’s not easy to picture him dealing with callers for three hours a day, five days a week.

Believe me, Mr. Mayor, it’s harder than it looks.
