It seems that Obama has been shortchanging his female Senate staffers :

Obama’s 28 male staffers divided among themselves total payroll expenditures of $1,523,120. Thus, Obama’s average male employee earned $54,397.
Obama’s 30 female employees split $1,354,580 among themselves, or $45,152, on average.

Even though he’s touting his support of mandating equal pay for women in the workplace and even though he charged that McCain doesn’t support equal pay for women:

Obama responded Aug. 31 to Alaska Gov. Sarah Palin’s Republican vice-presidential nomination. Palin “seems like a very engaging person,” Obama told voters in Toledo, Ohio. “But I’ve got to say, she’s opposed – like John McCain is – to equal pay for equal work. That doesn’t make much sense to me.”

But McCain actually pays his female Senate staff more than the males:

McCain’s 17 male staffers split $916,914, thus averaging $53,936. His 25 female employees divided $1,396,958 and averaged $55,878.
On average, according to these data, women in McCain’s office make $1.04 for every dollar a man makes. In fact, all other things being equal, a typical female staffer could earn 21 cents more per dollar paid to her male counterpart – while adding $10,726 to her annual income – by leaving Obama’s office and going to work for McCain.

Typical Democrat behavior! Mandating practices that they don’t follow themselves. This would make a good campaign ad, don’t you think?
