A national survey conducted by InsiderAdvantage from Aug. 15-17 shows 54 percent of registered voters approve of President Donald Trump’s job performance, versus 44 percent who disapprove, giving the Republican a net-positive rating of 10 points. The poll, which has a margin of error of 3.1 percentage points, is the first from the firm this year to place Trump above the 50-percent threshold. InsiderAdvantage finds Trump in positive territory with every age group under 65, buoyed by gains among African-American and Hispanic voters. Only the oldest cohort, those 65 and above, remains more negative than positive on his performance, continuing a pattern observed in the firm’s earlier surveys. The upbeat reading contrasts with other recent polls released over the past week. Rasmussen Reports put presidential approval at a breakeven 49-49, while surveys by RMG Research, Quantus Insights, Morning Consult, YouGov, Navigator Research and Pew Research range from net-3 to net-22 negatives. Separately, an RMG survey this month found 52 percent of Americans say they are not better off than they were four years ago, compared with 43 percent who feel better off. At the district level, a McLaughlin poll of Kentucky’s 4th Congressional District shows Trump enjoying an 87 percent approval rating among Republicans, far outpacing the 39 percent figure recorded for the area’s congressman, Thomas Massie. The results underscore the former president’s continued popularity with the party’s base even as individual lawmakers attract more mixed reviews.
