I think Trump (should he win in 2024) lost any opportunity to have competent cabinet secretaries when Mitch McConnell was reelected. Trump won’t get anyone through the senate that isn’t approved by McConnell and his fellow travelers. McConnell will do everything that he can to thwart Trump.
Lot of people here seem to forget Mitch had gatekeeper powers over appointments required by Senate approval.
Most of Trump’s interim picks were excellent because he could choose them.
