With 99 days to go until Election Day, Hillary Clinton leads Donald Trump by 9 percentage points in a national CNN/ORC poll out Monday surveying registered voters nationwide in the days after the Democratic National Convention.

Clinton and her running mate Virginia Sen. Tim Kaine grabbed 52 percent, while 43 percent said they would vote for Trump and Indiana Gov. Mike Pence. That's quite a shift from last week's poll following the Republican National Committee, when Trump led Clinton by three points head-to-head (48 percent to 45 percent) after trailing by seven points earlier in July.


With Libertarian nominee Gary Johnson and Green Party candidate Jill Stein listed as options, Clinton’s margin over Trump is roughly the same, at 8 points (45 percent to 37 percent). Johnson took 9 percent, while Stein earned 5 percent.

The poll, taken in the days after the Democratic National Convention, also suggested that public opinion of Clinton’s policy platform improved from the four-day gathering in Philadelphia. In mid-July, 43 percent of registered voters surveyed said they thought Clinton’s proposals would move the country in the right direction, compared with 48 percent who said the same after the DNC.

For Trump, meanwhile 38 percent said his policies would move the United States in the right direction, while 59 percent said they would move them in the wrong direction, largely in line with voters’ perceptions of his ideas before either convention.

Nearly half — 49 percent — of registered voters said what they read or saw about the DNC makes them more likely to vote for Clinton, the fourth-highest share responding that way in more than 30 years of CNN/ORC and Gallup polling.

Clinton’s supporters are also more certain that they will vote for the Democratic nominee in the fall, as 44 percent of registered voters backing the former secretary of state say they have already made up their minds and just 8 percent said they could change their mind. Among Trump voters, 36 percent said they have firmly decided on Trump, and a similar 7 percent said they could change their mind.

Clinton’s acceptance speech was received essentially the same as Trump’s the previous week, with 44 percent of registered voters calling it excellent or good, 20 percent “just OK” and 19 percent deeming it poor or terrible. The previous CNN/ORC poll showed that 40 percent said Trump’s speech was excellent or good.

Elsewhere, Clinton largely erased Trump’s gains after Cleveland, outperforming the Republican nominee on nearly every measure, except for honesty and trustworthiness.

With respect to Kaine, the Virginia senator’s favorability rating among registered voters increased 8 points from the previous week, 31 percent to 39 percent. While Pence enjoyed a larger 13-point bump in last week’s survey after the RNC (from 26 percent to 39 percent), the share of registered voters with a favorable opinion of the Indiana governor fell to 29 percent in the latest poll.

The poll was conducted July 29-31 via landlines and cellphones, surveying 1,003 adults nationwide with an overall margin of error of plus or minus 3 percentage points. The sample includes 894 registered voters, with a margin of error of 3.5 percentage points.
