Early in their marriage, President Bush and Laura Bush (search) would fight now and then over money. But they seldom argue about anything these days, the first lady says.

"When you have an opponent in a political race, it doesn't need to be your spouse," Mrs. Bush said during an appearance on the daytime talk show "Live With Regis and Kelly."

"I think maybe money was something we argued about earlier in our marriage," Mrs. Bush said. "I would want to buy something and he wouldn't."

Since moving to the White House, she said, money hasn't been an issue. "I don't know why, maybe because we don't really ever buy anything any more," she said.

The Bushes listed $822,126 in adjusted gross income on their 2003 returns. A former oil company executive, major league baseball owner and governor of Texas, Bush listed among his assets his beloved 1,583-acre Texas ranch, worth between $1 million and $5 million. He also has U.S. Treasury notes valued at $5 million to $8.7 million.

Mrs. Bush said she thought her husband's performance during the presidential debates "was great." Still, she acknowledged she was nervous.

"I get unbelievably nervous, much more nervous than he does, I think," she said.
