Last week's edition of the same poll showed Clinton, the Democratic nominee, ahead by 4 points, 42 percent to 38 percent.

Clinton's support is down 5 points from a high of 44 percent in the Rasmussen poll taken in early August, shortly after the Democratic National Convention.

Clinton has led in nearly all recent polls. But the race has tightened in recent days, according to the RealClearPolitics average of polls. Clinton still leads Trump by 4.6 points nationally, according to that average.

Rasmussen Reports conducted its poll of 1,000 likely voters via online and telephone interviews from Aug. 29 to Aug. 30. It has a margin of error of 3 percentage points.
