A new poll shows Hillary Clinton may be having some success in winning over supporters of Bernie Sanders.

According to a new nationwide CBS News poll released Monday, 73 percent of voters who backed Sanders during the primaries said they would vote for Clinton in November. Before the Democratic National Convention, that number was lower, at 67 percent.

Last week, the two were tied 42-42 following the Republican National Convention, and they were tied 40-40 two weeks ago.

Over half of voters continue to have an unfavorable opinion of Trump, despite a bounce after the RNC, but 31 percent still view him unfavorably.

The telephone-based poll of 1,393 adults was conducted July 29-31. The sample includes 1,131 registered voters. The margin of error on the entire sample is plus or minus 3 percentage points. The margin of error for the sample of registered voters is plus or minus 3 percentage points.
