“But what do the polls say? The race probably is tightening — but perhaps not as much as the hype on the cable networks would imply. In our polls-only forecast, Trump has narrowed Clinton’s lead in the popular vote to roughly 6 percentage points from 7 points a week ago, and his chances of winning have ticked up to 17 percent from 13 percent. In our polls-plus forecast, Trump’s chances are up to 19 percent from 16 percent.

Because of the high level of uncertainty in the race, we can’t say the door is closed on a narrow Trump victory. And we’re certainly a week or two removed from the period when every poll brought good news for Clinton: Plenty of polls now show negative trend lines for her (in addition to others that show a positive trend). But the race hasn’t fundamentally changed all that much.”
