The race stands at 46-45 percent, Clinton-Trump, in the latest results, so tight that the draw by third-party candidates Gary Johnson and Jill Stein could matter. Clinton, +1 vs. Trump in a four-way trial heat, is +3 head-to-head –- not a significant difference, but suggestive.
About a third of likely voters say they’re less likely to support Clinton given FBI Director James Comey’s disclosure Friday that the bureau is investigating more emails related to its probe of Clinton’s use of a private email server while secretary of state. Given other considerations, 63 percent say it makes no difference.
Those who say the issue makes them less apt to back Clinton overwhelmingly back Trump in the first place. But what’s key in a close contest is whether the disclosure gives Trump supporters further motivation to turn out for him –- and whether it demotivates reluctant Clinton backers.
