Elizabeth Warren has been so prodigious in raising money for her Senate campaign in Massachusetts that she is on track to become the top fund-raiser for the Senate this year, as well as one of the top Congressional fund-raisers of all time.

Ms. Warren’s haul — $24.5 million so far — has already catapulted her to No. 15 on the list of most successful Senate money-raisers in history, according to an analysis by the Center for Responsive Politics done for The New York Times. With more than three months to go before Election Day, she is likely to climb higher.

“She has become a darling for the left, and a lot of that money is incredibly frustrated and is looking for a place to go,” said Meredith McGehee, policy director of the Campaign Legal Center, a watchdog group in Washington.

Jon S. Corzine, a New Jersey Democrat, amassed $63.2 million in his successful 2000 Senate campaign, the most ever. But almost all of that came from his own wallet; Ms. Warren, by contrast, has not spent a dime of her own money. Excluding money put in by candidates themselves, Ms. Warren rises to No. 11.
