Republican Donald Trump has argued he’s the best candidate for president because he knows how the nation’s tax laws work and, therefore, can fix them.

The tax code gives the nation’s wealthy many more ways to shelter their earnings than the average American, who made a median $51,939 in 2013 and had a net worth ranging from $4,151 to $48,921, depending on age and excluding home equity.

But can wealthy politicians really feel the common man’s pain? And will they do anything about it?

Trump has claimed a $10 billion fortune though others have estimated his worth at $4 billion. His net worth, however, remains a mystery because he has refused to release his tax returns, breaking a 40-year tradition among presidential candidates.

Whether it’s $10 billion or $4 billion or less, that still makes Democratic rival Hillary Clinton a relative piker with just $15.3 million. And many members of Congress eclipse her wealth, hands down.

Here is a list of the 10 wealthiest members of Congress up for re-election, according to Yahoo Finance and Money & Career Cheatsheet:

Rep. Darrell Issa, R-Calif., $464 million: Issa built his fortune through his car alarm company, Directed Electronics, founded in the mid-1990s.

Rep. Jared Polis, D-Colo., $197.9 million: Polis headed information technology company American Information Systems while he was still a student at Princeton University in New Jersey.
