Sen John kerry + minimum net worth + $193.07 million, Kerry has appeared at or near the top of Roll Call's annual survey for 15 years, but even a modest uptick in his reported wealth couldn't earn him the No. 1 spot this time around.

As with many of the wealthiest members of Congress, much of the Massachusetts senator's wealth is attributable to his spouse. Kerry is married to Teresa Heinz Kerry, widow of the late Sen. John Heinz, R-Pa., an heir to the ketchup fortune.

Although Heinz Kerry's fortune has been estimated at several times the minimum figure listed in the senator's annual public reports, it is impossible to estimate based on those records.

Members are permitted to report assets held solely by a spouse in a special category designated only as "over $1 million," with no limit on the actual value of the asset. More than 140 items on Kerry's disclosure this year fell into that category.
