PRINCETON, NJ -- Gallup Poll Daily tracking from June 23-25 finds Barack Obama and John McCain tied for the second straight day in national registered voter preferences for the fall election, each winning 44% of the vote.
Today's results are consistent with Wednesday's finding of a tie at 45%. Additionally, Obama and McCain have been roughly tied in each individual day's results including in today's three-day rolling average, indicating some stability in the race since Monday.

The gap in support for the two presumptive major party nominees over the past week has been less than the four percentage point margin of sampling error needed for one of the candidates to demonstrate a statistically significant lead, thus the race has been fairly close. However, until Wednesday's tie, based on interviewing conducted June 22-24, Obama held the slight advantage. -- Lydia Saad

In addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls.
