Dick Durbin Says Minimum Wage Increase Will Give Workers More Purchasing Power

Senator Dick Durbin doesn't believe the demand for labor is a downward sloping curve. WJOL reports:

U.S. Senator Dick Durbin is on board with the state's plan to raise the minimum wage to ten-bucks-an-hour. He says it'll innovate the economy and give workers more purchasing and spending power. The minimum wage is set at eight-25 in Illinois now, but Governor Quinn and Democrats have been trying to boost it. They say people shouldn't work 40-hours-a-week and still live in poverty. Voters will be allowed to weigh in on the issue when they head to the polls on November 4th.

Why not $25 an hour Senator Durbin? Why do Illinois Democrats need a referendum to encourage Illinois politicians to vote an increase?
