There's no dispute that Mitt Romney is wealthy. But what is the presumptive GOP presidential nominee really worth?

Forbes magazine tries to get an answer with its analysis of 184 assets listed on Romney's personal financial disclosure report. The magazine's answer: $230 million.

The value of assets on these reports are listed in broad ranges, which makes it difficult to nail down how much is actually there. Romney's net worth has typically been reported as $190 million to $250 million, based on those reports.

President Obama and Vice President Biden released their latest financial disclosure reports yesterday. Obama's assets are worth at least $2.6 million and could reach $8 million or more.
