His poll numbers have been sagging. The Republicans have thwarted many of his policy goals. But President Obama is still optimistic. He told supporters on Wednesday that more change will come if they keep working hard to help him get reelected. "If you're willing to work even harder in this election than you did in the last election, I promise you, change will come," Obama said. The president added that he’s not a “flawless” or perfect candidate, but he’s had success because of those who support him. The president attended three fundraisers in Chicago and made a surprise visit to his campaign headquarters to thank his staff for their hard work.
