For Reuters, John Whitesides reports on this morning's new Zogby poll:

Bush and Kerry were tied at 47 percent in the latest three-day national tracking poll as the Massachusetts senator gained two points on Bush. Bush led Kerry 48-46 percent on Thursday.

The deadlock sets up a frantic race to Tuesday's finish in another tight U.S. presidential election, with neither candidate able to establish a clear advantage or break 50 percent.

Only 3 percent of likely voters remain undecided. At this stage of the disputed 2000 election, Bush led Gore by three points in the daily tracking poll.

Bush gained ground in some of the critical swing states that will decide who accumulates the 270 electoral votes needed to win, leading in five of the 10 battleground states surveyed in a series of Reuters/Zogby state tracking polls.

Bush led in Florida, Michigan, Minnesota, New Mexico and Nevada, while Kerry was ahead in Colorado, Iowa, Ohio and Wisconsin. The crucial state of Pennsylvania was tied.
