Barack Obama narrowly leads John McCain in five of eight crucial battleground states one week before the U.S. presidential election, with McCain ahead in two states and Florida dead even, according to a series of Reuters/Zogby polls released on Monday.
Obama held a steady 5-point national lead over McCain among likely U.S. voters in a separate Reuters/C-SPAN/Zogby tracking poll, the same advantage he held on Sunday. The national telephone poll has a margin of error of 2.9 percentage points.
