One sign that the Democrats will raise the Supreme Court as a campaign issue will come Tuesday night when Lilly Ledbetter addresses the Democratic national convention in Denver. Ledbetter, you may recall, was a Goodyear tire worker who lost a 2007 Supreme Court case based on her claim of unequal pay (pdf).

The justices, in one of the most criticized rulings of the Roberts Court, ruled that her claim was untimely because it was filed long after the initial pay decision was made. She worked for the company for more than a decade before realizing the disparity. Democrats reacted with outrage, and Ledbetter became a symbol of the effects of the Supreme Court’s conservative turn.
