Mitt Romney may have more money than any other presidential candidate in the race, but his wife said today that she does not consider herself wealthy.

"We can be poor in spirit, and I don't even consider myself wealthy, which is an interesting thing," Ann Romney said in an interview on Fox News. "It can be here today and gone tomorrow."

Romney's comment came during a discussion about her battle with Multiple Sclerosis, and specifically in response to a question from Fox's Neal Cavuto about whether the Romneys are "oblivious, given your wealth, to the everyday concerns of average folks."

"How I measure riches," Romney continued, "is by the friends I have and the loved ones I have and the people that I care about in my life, and that's where my values are and that's where my riches are."

According to his tax returns, Romney brought in about $42 million in 2010 and 2011. His estimated net worth is around $200 million.

Mitt Romney has been criticized as " out of touch" for a handful of comments he has made referencing his immense wealth on the campaign trail.

When an Associated Press reporter asked if Romney followed any specific NASCAR drivers while the candidate was touring a NASCAR team owners' Daytona 500 facilities last week, Romney said he didn't follow drivers, ""but I have some great friends who are NASCAR team owners."

And during a campaign speech in Michigan, Romney mentioned that Ann "drives a couple of Cadillacs." When asked later if he thought these two comments hurt his campaign, Romney simply responded, "Yes."
