The latest public opinion polls show President Bush and challenger John Kerry back in a virtual tie two weeks before the U.S. presidential election.
The daily tracking poll by Zogby International shows the candidates locked at 45 percent among likely voters, with seven percent undecided.
A New York Times poll of likely voters gives the president a two percent lead, within the poll's three-point margin of error.
And Mr. Bush has a three-point lead in a Washington Post poll, right on the edge of that survey's three-point margin of error.
Some other polls in recent days showed the Republican incumbent building a small lead over his Democratic Party opponent.
Voting has already begun in more than 20 U.S. states that give residents the option of early voting.
