The new poll by the Pew Research Center points to a particular challenge for Republican presidential candidate Mitt Romney. His party's policies are viewed by most as favoring the rich over the middle class and poor.
The poll found that many Americans believe rich people are intelligent and hardworking but also greedy and less honest than the average American. Nearly six in 10, or 58 percent, say the rich don't pay enough in taxes.
Even among those who describe themselves as "upper class" or "upper middle class," more than half said upper-income Americans don't pay enough taxes.
