Ohio, Long a Bellwether, Is Now Fading on the Electoral Map.  (The New York Times, 9/29/2106)

But its Rust Belt profile, Mr. Trump’s unyielding anti-trade campaign and Mrs. Clinton’s difficulty energizing Ohio’s young voters have made it a lesser focus for Democrats this year, even as it remains critical to Mr. Trump’s path to the White House. As Mrs. Clinton’s aides privately note, the demographic makeup of Florida, Colorado and North Carolina, which have a greater percentage of educated or nonwhite voters, makes those states more promising for Democrats in a contest in which the electorate is sorted along bright racial and economic lines.
