Senate Democrats get burned in pay for workers debate

This whole issue of underpaying female workers is nuts.  The very fact that Democratic politicians are paying their female staff less than their male staff makes it hard to believe that there is anything other than supply and demand going on here.  I don't believe that female Democratic Senators don't appreciate women workers.  From the Free Beacon (it is a long article):

A group of Democratic female senators on Wednesday declared war on the so-called “gender pay gap,” urging their colleagues to pass the aptly named Paycheck Fairness Act when Congress returns from recess next month. However, a substantial gender pay gap exists in their own offices, a Washington Free Beacon analysis of Senate salary data reveals.
Of the five senators who participated in Wednesday’s press conference—Barbara Mikulski (D., Md.), Patty Murray (D., Wash.), Debbie Stabenow (D., Mich.), Dianne Feinstein (D., Calif.) and Barbara Boxer (D., Calif.)—three pay their female staff members significantly less than male staffers.
Murray, who has repeatedly accused Republicans of waging a “war a women,” is one of the worst offenders. Female members of Murray’s staff made about $21,000 less per year than male staffers in 2011, a difference of 35.2 percent. . . .
A significant “gender gap” exists in Feinstein’s office, where women also made about $21,000 less than men in 2011, but the percentage difference—41 percent—was even higher than Murray’s. . . .
The employee gender pay gap among Senate Democrats was not limited to Murray, Boxer, and Feinstein. Of the 50 members of the Senate Democratic caucus examined in the analysis, 37 senators paid their female staffers less than male staffers. . . .
