Details: The center, which is launching its 2020 program Thursday, looked at historical turnover data for high-level positions requiring Senate confirmation from Presidents Bill Clinton, George W. Bush and Barack Obama, each of whom was elected to a second term.

Each had lower turnover levels than Trump at this point in their tenure, measured across 15 Cabinet-level departments.

Each also saw a spike in resignations in Year 5, typical as first-term officials reach levels of exhaustion and incumbents seek fresh eyes and energy, the center’s new director David Marchick told Axios.

On average, 43% of top officials serving near the end of the first term left within the first six months after the incumbent presidents’ re-elections.
