I'm betting his wife has had more than a few meals at Wendy's...
 
 
 No Sour Milk for Edwards 
 
 Trying to prove himself as the down-to-earth American that he argues Dick Cheney is not, Democratic vice presidential candidate John Edwards was grilled on his everyday know-how on Don Imus's radio show yesterday morning. 
 "Well, what do you think a gallon of milk costs in Albuquerque?" Imus asked. 
 "I think a half a gallon of milk costs about $2.30, $2.40, is that right?" responded the multimillionaire trial lawyer-turned-senator. 
 "Actually, it costs $4.19," Imus said. (Come to find out Edwards was right on the money: It's pertinent to note, as the Associated Press did, a half-gallon of milk at the Safeway in Edwards's Georgetown 'hood costs $2.29.) 
 As for beer, Johnny-boy owned up to his naivete. "I have to be honest with you, I haven't drank a six-pack of beer in a long time, so I don't know the answer to that." Fair enough. 
 But we bet he can tell you the price of a Wendy's cheeseburger. (Though its 99-cent menu does help.) He and wife Elizabeth have been celebrating every wedding anniversary at the fast-food chain going on 27 years now.
