Exit polling suggests that Romney may have to broaden his appeal to middle-class voters.
He has consistently performed better than his rivals among voters with higher family incomes. Although Romney has lost the overall vote in eight of the 18 states where exit or entrance polls were conducted, he only lost voters with six-figure incomes in three of them.
In Louisiana, the high-dollar tilt in Romney's support was particularly pronounced: A majority of those who voted for Romney had six-figure family incomes though that group made up just three in 10 voters.
He's trying to broaden his appeal, in part, by chatting about gambling.
"We were talking about that. I guess there is a massive, massive lottery," Romney said while visiting a restaurant Friday evening as Mega Millions ticketholders across the country awaited a record drawing. "I'm not planning on playing the lottery."
With a dry smile, he took a shot at a mega-donor and casino mogul who supports Newt Gingrich's campaign. "I understand that Sheldon Adelson has bought some tickets," he said.
