Clinton is seen unfavorably by 60 percent of likely voters in the latest results, a new high. Trump is seen unfavorably by essentially as many — 58 percent. Marking the depth of these views, 49 percent see Clinton “strongly” unfavorably, and 48 percent say the same about Trump –- unusual levels of strong sentiment.

The extent of partisan antipathy in this poll, produced for ABC by Langer Research Associates, is remarkable: Ninety-seven percent of Trump supporters see Clinton unfavorably; 90 percent, strongly so. Ninety-five percent of Clinton supporters see Trump unfavorably -– again, 90 percent strongly so.

Beneath these results is a possible slip in enthusiasm for Clinton: Using just the last two nights’ results -– after FBI Director James Comey revealed a further Clinton-related email investigation -– 47 percent of her supporters say they’re very enthusiastic about her, compared with 51 percent across the previous six nights.

Overall vote preferences haven’t changed since Comey’s announcement, and the change in strong enthusiasm for Clinton is not statistically significant and could reflect night-to-night variability. Still, it bears watching.
