WASHINGTON (AP) — Democrats are growing increasingly confident in their two-pronged tax attack on Republican Mitt Romney. They're hammering both his policies and personal taxes, aiming to help President Barack Obama win pivotal support from middle class voters.
Led by Obama, the Democrats' summer assault goes after Romney for seeking to protect tax cuts for the rich and for refusing to release more information on the taxes he pays on his personal fortune.
Democrats say public and private polling suggests the double-barreled focus on taxes is a political winner for the president.
Republicans reject the notion that Romney's tax proposals could hurt him in the fall. But some party operatives say he is being damaged by his decision not to release more than two years of tax returns.
