Republican presidential nominee Donald Trump leads Democratic presidential nominee Hillary Clinton by just over half a percentage point in the USC Dornsife/Los Angeles Times "Daybreak" poll, which is updated daily.
Saturday's data has Trump just ahead of Clinton, 44.2 to 43.6.
The poll tracks about 3,000 eligible voters until election day, the Times notes, asking them regularly about candidate support in addition to likelihood of voting.
In regard to Saturday's percentages, the respondents are asked, "Who would you vote for?"
"We ask voters what the chance is that they will vote for Trump, Clinton or someone else, using a 0-100 scale," the poll description notes. "The overall level of support for each candidate reflects the weighted average of those responses."
The poll description adds that data is updated daily "based on the weighted average of poll responses over the previous week. That means results have less volatility than some other polls, but also means the poll lags somewhat in responding to major events in the campaign."
