Trump’s job approval rating is 37 percent in this poll, produced for ABC by Langer Research Associates; that’s down four percentage points from October and a point from his career low. He’s got the lowest two-year average approval rating on record for a president in polls back 72 years (38 percent) compared with an average of 61 percent for the 12 previous presidents since 1945.

Among groups, Trump’s dropped to a new low of 27 percent approval among women, down 9 points since November, led by a 13-point drop among college-educated white women; his rating is a broad 22 points higher among men: 49 percent. And at 32 percent approval, his rating among political independents, often the swing group in U.S. politics, matches its low.

The study, which was conducted by The Chicago Council on Global Affairs between January 11 and 13, found that 55 percent of Americans were opposed to expanding the existing border between the U.S. and Mexico with Trump's border wall and fencing, while four in 10 (41 percent) were in favor of the idea.
