Obama says he would cut taxes for middle class

clipped from hosted.ap.org Democrat Barack Obama told voters Saturday he would push an aggressive economic agenda as president: cutting taxes for the middle class, raising taxes on the wealthy, pouring money into "green energy" and requiring employers to set up retirement saving plans for their workers. Campaigning in Pennsylvania, a key battleground in the fall campaign, Obama said he would take a much more hands-on approach than would Republican John McCain. He again criticized McCain's proposal for a temporary halt in the federal gasoline tax. It would "actually do real harm," Obama said, by reducing revenue for road and bridge construction even as oil companies make record profits.
