Hillary Clinton is back on top of Donald Trump in the latest CNN/ORC national survey of registered voters, which shows the Democratic presidential nominee has received a 7-point bump following her party's convention.

Clinton now leads her Republican opponent 45 percent to 37 percent in a four-way matchup against Libertarian nominee Gary Johnson (9 percent) and Green Party candidate Jill Stein (5 percent). A pre-convention survey showed her trailing Trump 39 to 44 percent.

The former secretary of state has also improved her popularity among independent voters, who Trump carried an 18-point lead with heading into the Democratic convention. Clinton is now ahead of Trump by 4 percentage points (37/33) among independents.

On the heels of their convention, which began with the resignation of Florida Congresswoman Debbie Wasserman Schultz as chairwoman of the Democratic National Committee, Democrats appear more confident in their party's ability to unite ahead of the November election.

Eighty-four percent of Democrats and left-leaning independents said their party will be unified come election day, marking a 9-point increase from a survey taken before both parties' conventions.

Trump, whose post-convention bump was around eight percentage points, still leads Clinton as the candidate more voters see as honest, but his favorability rating took a dive after both conventions. While the percentage of voters who hold a positive view of Clinton remains the same now as before the conventions (43 percent), Trump's rating has dipped from 39 percent favorable and 59 percent unfavorable to 35-61.

The CNN/ORC survey of 894 registered voters was conducted July 29-31. Results contain a margin of error plus or minus 3.5 percentage points.
