Obama, McCain remain in statistical tie

PRINCETON, N.J., Aug. 23 (UPI) -- Barack Obama and John McCain remain in a statistical tie in their race for the U.S. presidency, a Gallup tracking poll released Saturday finds.

Registered voters surveyed Wednesday through Friday went for Obama by 46 percent and McCain by 44 percent. While Obama continues to run slightly ahead, his lead has not been statistically significant since Aug. 10.

Obama announced Saturday that Sen. Joseph Biden of Delaware is his choice for vice president. Jeff Jones, Gallup's managing editor, said that announcement is likely to be followed by a small bounce in his numbers that will start to enter Gallup's numbers Sunday and be fully reflected in Tuesday's report.

In 2004, neither President George Bush or the Democratic nominee, U.S. Sen. John Kerry of Massachusetts, got a significant post-convention bounce. The McCain campaign has been predicting a large bounce for Obama, presumably to make political hay if he fails to get one.
