(CNN) - Sen. Barack Obama has his largest lead so far over rival Sen. John McCain, according to CNN’s latest national poll of polls.
Obama leads McCain by nine points in the poll of polls released Tuesday – 51 percent to 42 percent. Seven percent of those surveyed are unsure about their choice for president.
In Monday’s CNN’s poll of polls, Obama’s lead over McCain was seven points – 51 percent to 44 percent.
“Today’s Poll of Polls average reflects the fact that Obama has moved into a commanding position in the presidential race,” said CNN Senior Political Researcher Alan Silverleib. “Obama is either tied or ahead in all of the battleground states. The Democrats now have what may be a decisive edge in terms of voter enthusiasm and financial resources. The financial meltdown has played to Obama’s advantage. By most measurements, McCain was not able to use the debates to gain ground on Obama. And most of the campaign is now being waged in previously red states. While anything can happen in the remaining two weeks, it’s hard not to conclude that McCain’s back is against the wall.”
Tuesday’s CNN poll of polls is composed of the following six national general election surveys of likely voters: Pew (October 16-19), CNN/ORC (October 17-19), ABC/Washington Post (October 16-19), Reuters/C-SPAN/Zogby (October 18-20), Gallup (October 18-20) and Diageo/Hotline (October 18-20). The poll of polls does not have a sampling error.
