Hillary Clinton continues to have the upper hand over Donald Trump in the presidential race, another poll released Monday shows.
The CNN Poll of Polls incorporating the results of six major polls -- all conducted after the party conventions concluded in late July -- finds Clinton with an average of 49% support to Trump's 39%.
When third party candidates Gary Johnson and Jill Stein are included, the margin remains the same, with both candidates losing the same amount of support to land at 45% for Clinton to 35% for Trump, with Johnson at 9% and Stein at 5%, according to CNN.
The new averages reflect a sharp increase in support for Clinton compared with pre-convention polls. The last CNN Poll of Polls, analyzing the results of five national, live-interviewer telephone polls conducted before the GOP convention began, found Clinton ahead 45% to 41%.
Polls released early last week found that Clinton had a lead ranging from anywhere between 7% in a CBS poll to as high as 9% in CNN/ORC's poll.
But a Reuters/Ipsos released on Friday showed that her lead over Trump had shrunk to less than 3 percentage points.
The candidate holding a lead after both major party conventions are complete nearly always goes on to win the presidency in recent history, noted CNN. One exception was Al Gore in 2000, who held a 4-point lead in CNN/USA Today/Gallup poll conducted after the completion of his convention. Gore, the sitting vice president at the time, went on to win the popular vote by about half a percentage point while losing to George W. Bush in the Electoral College.
This CNN Poll of Polls covers polls conducted between July 29 and August 4. All were conducted by telephone using live interviewers, with results representing the opinions of registered voters nationwide.
Polls included are the CNN/ORC Poll, the CBS News Poll, the Fox News Poll, the NBC News/Wall Street Journal Poll, the Marist/McClatchy Poll and the ABC News/Washington Post Poll. The Poll of Polls does not have a margin of sampling error.
