DENVER, Colorado (CNN) – A new national CNN poll of polls suggests Barack Obama has a modest 4-point lead over John McCain in the battle for the White House.
In the survey, compiled Sunday morning, 46 percent of those questioned said that Obama, D-Illinois, is their choice for president, with 42 percent backing Sen. John McCain, R-Arizona. Twelve percent of those polled are undecided.
Obama had a 2-point lead in the last poll of polls, compiled late last week.
CNN’s poll of polls is an average of the latest national polls. Today’s edition consists of three surveys: an ABC/Washington Post poll taken from August 19-22, a Fox/Opinion Dynamics survey taken on August 19 and 20, and a Gallup tracking poll taken from August 20-22.
Since most of the polling was conducted before Sen. Joe Biden of Delaware was named as Obama’s running mate, it’s too early to tell if his joining the Democratic ticket will make any difference in the polls.
But a new USA Today/Gallup poll out Sunday morning suggests that Biden may not make a major impact on the race for the White House. Fourteen percent of those question say that having Biden on the Democratic ticket makes them more likely to vote for Obama in November, with 7 percent saying it will make them less likely, and 72 percent saying Biden’s pick will not have much impact on their vote.
Twenty-three percent of those questioned in the poll say they’ve never heard of Biden, who’s the chairman of the Senate Foreign Relations Committee and who was a presidential candidate before dropping out of the race in January.
Twenty-eight percent of those polled say they have no opinion of Biden. The USA Today/Gallup poll was conducted Saturday, after news of Biden’s selection came out.
