The campaign for Virginia governor has divided voters along demographic lines highly reminiscent of last November’s presidential election, according to a New York Times Upshot/Siena College poll on Sunday, and the Democrat, Ralph Northam, holds a modest three-point lead over the Republican, Ed Gillespie, 43 percent to 40 percent…

White voters without a college degree backed Mr. Gillespie by a 40-point margin in the poll, 63 percent to 23 percent, while nonwhite voters backed Mr. Northam by a similar margin, 65 to 17. Mr. Northam holds roughly a 10-point lead among college-educated white voters, enough to give him the edge statewide.

But neither Mr. Northam nor Mr. Gillespie appears to be matching Donald J. Trump or Hillary Clinton’s huge margins among their strongest demographic groups.
