A new poll out Wednesday showed Donald Trump leading Hillary Clinton 47 to 40.4 percent — his largest margin yet in the presidential race.

The results of the USC/Los Angeles Times poll likely reflect the so-called “bounce” candidates get immediately after their party’s convention.

The results also follow FBI Director James Comey’s disclosure in July that Clinton was “extremely reckless” using private e-mail to conduct government business while serving as secretary of state.

Clinton is expected to get a boost of her own after this week’s Democratic National Convention in Philadelphia.

Other recent polls reflect a tighter race, with the RealClearPolitics average showing Trump barley leading the former first lady, 45.7 to 44.6 percent.

The USC/LA Times survey tracks the opinions of about 3,000 people who have agreed to participate.
