Senate Republicans decided not to block the advancement of the Paycheck Fairness Act.

Democrats needed 60 votes to advance the legislation procedurally; the tally was 73-25 on Wednesday.

The move will once again tie up the Senate in debate for days. 

More than 15 Republicans voted to end debate on the motion to proceed to S. 2199, despite all Republicans voting against it in April. Republicans used similar tactics earlier this week in allowing a constitutional amendment on campaign spending to advance.

Senate Democrats said they were giving Republicans another opportunity to ensure women receive equal pay for equal work.

The Paycheck Fairness Act is part of Democrats’ Fair Shot agenda — progressive priorities meant to draw distinction between the two parties ahead of November’s elections. The Senate is also expected to vote on raising the minimum wage and allowing students to refinance their loans — all measures that have already failed this year.

Republicans have accused Democrats of voting for the sake of PR while the Senate has only two weeks to legislate before adjourning for midterm campaigning. The Senate will have to use that time to pass a short-term continuing resolution to keep the government funded after Sept. 30 and reauthorize the Export-Import Bank.

Democrats have benefitted from a gender gap at the polls, and the party hopes that by emphasizing certain issues, it will be positioned to take advantage on Nov. 4.

Democrats outperformed Republicans among women voters in 2012, one of the reasons they picked up two Senate seats despite predictions they would lose ground. Democratic pollsters worry that low turnout, especially among unmarried women, will hurt the party this year.

The legislation punishes employers for retaliating against workers who share wage information, puts the justification burden on employers as to why someone is paid less and allows workers to sue for punitive damages of wage discrimination. 

It requires the Department of Labor to increase outreach and training with employers to eliminate pay inequality and to continue to collect wage information based on gender. 

The bill would also create a grant program to train women on wage negotiation skills.

Republicans said they opposed the legislation as a “giveaway” to trial lawyers because it would remove caps on punitive damages against businesses found guilty of discrimination.
