"I realize there are some wealthy individuals - I'm not one of them, but some wealthy individuals who have a lot of stock portfolios" she told him.

Hard to see how Warren wouldn't be, by most standards, wealthy, according to the Personal Financial Disclosure form she filed to run for Senate shows that she's worth as much as $14.5 million. She earned more than $429,000 from Harvard last year alone for a total of about $700,000, and lives in a house worth $5 million.

She also has a portfolio of investments in stocks and bonds worth as as much as $8 million, according to the form, which lists value ranges for each investment. The bulk of it is in funds managed by TIAA-CREF.

Warren would not, of course, be particularly wealthy by the tony standards of the Senate. But she's also unlikely to draw the sort of popular identification with her financial status that might attach to Marco Rubio, whose home is underwater.

And efforts to pass herself off as one of the 99% for whom she aims to speak appear likely to backfire.
