It's a Zogby poll.
McCain leads Obama by a 46% to 41% margin.
And McCain not only enjoys a five-point edge in a two-way race against Obama, but also in a four-way contest including liberal independent candidate Ralph Nader and Libertarian Bob Barr, the poll reveals. In the four-way contest, McCain wins 44% support, Obama 39%, Barr 3% and Nader 2%.
This latest Reuters/Zogby poll is a dramatic reversal from the identical survey taken last month – in the July 9-13 Reuters/Zogby survey, Obama led McCain, 47% to 40%. In the four-way race last month, Obama held a 10-point lead over McCain.
Here is how voters rated issues most important to them in choosing a President: economy 47%, War in Iraq 12%, energy prices 8%, healthcare 7%, threat of attack on the U.S. 6%, immigration 5% and the environment 4%.
