In 12 of 14 battleground states, a review of
RealClearPolitics’ polling averages found, support for Clinton dropped from October 27 (the day before the letter’s release) through November 3. Only in Maine has Clinton’s support risen since the day before the Comey letter. However, Maine is a rarity; it splits its electors by Congressional District, and Trump
is doing better in its Second Congressional District, where the race is tighter.
Iowa has had no polling since the Comey letter’s release. (See the end of this article for a detailed state-by-state breakdown.) The drops have been steepest in Nevada, Colorado, Virginia, New Hampshire, and Arizona.
In the national polling averages from
FiveThirtyEight and
RealClearPolitics, Clinton’s support fell 2.7 and 2.6 percentage points since the day before the Comey release.
Thus, it’s clear there’s been a tightening of the race in Trump’s favor since the letter came out.
