Sometimes it seems that political campaigns never end. In the case of some committees raising money for congressional campaigns, that’s literally true.

Even after members of Congress leave office, their campaign committees often keep churning along. In fact, three committees are still active even though the lawmakers that started them have died.

At least 141 former members of Congress retain campaign accounts containing a total of more than $46 million, a USA TODAY analysis found. Twenty are linked to campaign committees with more than $500,000 each. Nearly one-third of the ex-lawmakers have been out of office at least five years.

The committee run by former Michigan Democratic Sen. Don Riegle, 77, holds the record for longevity. It’s still active more than 20 years after Riegle left the Senate.
