LOS ANGELES -- Hillary Clinton and John McCain lead the latest national poll of US voters, boosting their frontrunner credentials in the race to become the Democratic and Republican candidates for president.
The survey, conducted by Los Angeles Times and Bloomberg News, shows Clinton with a nine-point lead over fellow Democrat Barack Obama, but her lead has shrunk from 24 points in the last Times/Bloomberg poll, in early December.
In the poll, released late Wednesday, New York Senator and former first lady Clinton was first among Democrats with 42 percent, Illinois Senator Obama was second with 33 percent and former senator John Edwards was third with 11.
However, the poll also found that about two-thirds of Democratic voters now say they are "certain" about who they will vote for, making last minute changes less likely, the Los Angeles Times said in its analysis of the numbers.
And should Edwards drop out -- he has not won any primaries thus far -- his supporters were more likely to defect to Clinton than Obama, the poll found.
The margin of error for the Democrats was plus or minus three percentage points. The poll was conducted January 18 to 22 among 1,541 adults.
Meanwhile, Senator John McCain led the Republican field with 22 percent, followed by former Arkansas governor Mike Huckabee (18 percent), former Massachusetts governor Mitt Romney (17 percent), and former New York mayor Rudi Giuliani (12 percent).
The margin of error for the poll's Republican figures was plus or minus five percentage points, blurring the distinction between the top three Republicans.
But the numbers were grim for Giuliani, who was the national frontrunner in every earlier edition of this poll.
The Republican race is too close to call, leading into the high-stakes January 29 Florida primary with its rich prize of 57 winner-take-all delegates to the Republican National Convention in September.
A poll of Florida voters Wednesday showed McCain with 25 percent heading into Tuesday's primary, and statistically tied with Romney on 23 percent.
Giuliani, who is staking his presidential campaign on Florida after all but ignoring the early nominating contests, trailed on just 15 percent, alongside Huckabee, in the St. Petersburg Times poll.
