Highlighting equal pay day is one way Democrats can win female voters next fall.
Today President Obama's bringing equal pay activist Lily Ledbetter back to the White House to watch him sign two new orders for federal contractors.
One prevents retribution for employees who speak out about what they're paid.
The other requires contractors to report compensation by race and gender. "The President is using his executive powers to do that the do nothing congress would not do," said Del. Eleanor Holmes Norton, (D) Washington D.C.

The Senate is due to vote on pay equity this week.
