There are some troubling signs for Donald Trump in Georgia, where a poll out Friday shows him running neck and neck with Hillary Clinton.

With 18 days to go before Election Day, a new Atlanta Journal-Constitution poll shows Mr. Trump, a Republican, with a 44-42 percent lead over Mrs. Clinton, a Democrat.

Georgia has not supported a Democrat in a presidential race since 1992, though Democrats have been eager to push the story line that the state has trending in their direction thanks to changing demographics.
