There are limits to frugality, unless you are Sestak

From The Morning Call:

Sestak pays his staff the least in Pennsylvania's Congressional delagation:

"He asks aides to work six days a week, 12-plus hours a day. Staff salaries are among the lowest on Capitol Hill, according to congressional records. No one in Pennsylvania's 19-member congressional delegation had a smaller payroll than Sestak in the 18-month period that ended June 30, records show, while only two members had larger staffs."

What does he do with the savings? Sounds like publicly financed campaigning to me:

"The money Sestak saves on staff salaries is in part devoted to constituent mailings and brochures highlighting his positions on issues. Sestak last year spent more on mail than anyone in the delegation."
