But Clinton’s advantage in the post-debate data is just as clear. Out of 20 post-debate polls in swing states, she’s led in 18, trailed in only one (today’s Quinnipiac poll of Ohio) and was tied in one other. Overall, the post-debate polls look a lot like the results that President Obama had against Mitt Romney in the 2012 election, although with Ohio and North Carolina flipping sides. (Iowa is a good candidate for Trump also, but it hasn’t been polled since the debate.) That isn’t a coincidence, since Obama beat Romney by 3.9 percentage points in 2012 — right about where our model has the Clinton-Trump gap now.
