Getty Poll: Clinton's lead over Sanders drops to 10 points

Hillary Clinton’s lead in the Democratic presidential primary has dropped to 10 points since last month, according to a new CNN/ORC national poll of registered voters released Thursday night.

The former secretary of state has the support of 37 percent of Democrats and Democratic-leaning voters, with Vermont Sen. Bernie Sanders at 27 percent.


Vice President Joe Biden, who has not yet declared whether he will run, polls at 20 percent. He is the sole presidential hopeful to make substantial gains in August, up 6 points.

Rounding out the field, Martin O’Malley, the former Maryland governor, is at 3 percent and former Virginia Sen. Jim Webb at 2 percent. Lincoln Chafee, the former governor of Rhode Island, polls under 1 percent.

Despite Clinton’s shrinking lead, 65 percent of those polled said they expected her to be the Democratic nominee.

The poll of 1,012 adult Americans, 930 of them registered voters, was conducted by landline and cell phone from Sept. 4-8, and has a margin of error of plus or minus 3 percentage points.
