What will Donald Trump's job approval rating be according to RealClearPolitics's Job Approval average at 11:00 AM ET on August 19, 2026, binned to the nearest 0.1 percentage point?

rationale:

Status Quo and Baseline The primary anchor for the August 19 reading is today's (August 18) baseline. While direct reads of the RealClearPolitics job approval page have shown fluctuations between 39.1% and 39.2% depending on the specific fetch 2 sources, prediction market settlement data for the August 18 11:00 AM ET cutoff priced the 39.1% bin overwhelmingly higher coinbase.com. Given this strong structural anchor, 39.1% serves as our most likely starting point at 29%, with 39.2% representing a highly plausible alternative at 21% if the average ticks back up or if recent page cache discrepancies resolve in that direction.

Methodology and Inertia RCP relies on a roughly dozen-poll rolling window stretching over approximately four weeks. Because of this large denominator, day-to-day movements are typically sluggish—usually constrained to between 0.0 and 0.2 points unless a flurry of uniquely skewed data is ingested simultaneously. This structural inertia heavily concentrates probability mass at and immediately adjacent to the current baseline of 39.1% and 39.2%.

Immediate Downside Pressure Despite the slow-moving average, the distribution requires a pronounced left skew due to an impending structural update and broader environmental factors. A newly released Reuters/Ipsos poll fielded August 14–17 recorded Trump's approval at just 33% 3 sources. If RCP incorporates this reading before the August 19 deadline—replacing a previous Reuters/Ipsos entry of 35% or 38%—simple substitution math suggests the overall average would decline by approximately 0.15 to 0.4 points. Should this new data point hit the tracker before 11:00 AM ET, the average would be aggressively pulled down toward the 39.0% (18%) and 38.9% (11%) bins, with a 10% chance of falling below 38.9%. Evaluating the broader political environment, including headwinds from border security and foreign policy issues, slightly increases expectations for this near-term drop in the approval average.

Synthesis and Upside Constraints The probability distribution balances the structural inertia of the status quo against the specific, measurable downside risk of the pending Reuters/Ipsos update and political headwinds. Because RCP can occasionally lag by one to three days in updating its tracker, the modal outcome remains an unchanged 39.1%. However, the left tail is significantly elevated to account for the mathematical reality of a new 33% poll entering a small-denominator average alongside negative broader pressures. Conversely, upside potential above 39.3% is severely limited; recent tracking generally skews low, and a fresh high-end outlier—a 44% Rasmussen poll realclearpolling.com—is already locked into the current window and will not roll off to elevate the average. This restricts expectations for 39.3% to a 7% probability, 39.4% to 2%, 39.5% to 1%, and above 39.5% to just 1%.
