Tracking poll: Presidential race tied

By CNN Polling Director Keating Holland

WASHINGTON (CNN) -- The presidential race is neck-and-neck in today's tracking poll, with just a single percentage point separating the two candidates. If the election were held today, 46 percent of likely voters would pick Vice President Al Gore and 45 percent would choose Texas Gov. George W. Bush, with Ralph Nader and Pat Buchanan in single digits.

The CNN/USA Today/Gallup poll of 752 likely voters conducted October 21-23 has a 4-point margin of error.

Bush enjoyed a temporary gain in the polls last week after the third and final presidential debate, as he did after the first debate, which faded after a few days back to a dead heat. Since Labor Day, the race has essentially been too close to call, with neither candidate able to hold onto a lead for more than a few days.
