Poll: Clinton 40, Trump 35, Johnson 8

As in previous polls, she maintains a double digit lead with women, political moderates and those under the age of 45. Among Hispanics, she is ahead by two to one and she has a 62-point lead with blacks. Trump has smaller, single-digit leads with white voters and political independents. The two are nearly tied with voters 45 and older.

Clinton has still not won over nearly half of those Democratic primary voters who supported Sanders in the nomination process, and less than half the GOP primary voters who favored candidates other than Trump would vote for him against Clinton. These groups are the source of much of the support for Johnson and others.
