From a story on politico.com by Adam Wren headlined “Mitch Daniels opts against a run for the Senate”:

Mitch Daniels is passing on a potential bid for an open Indiana Senate seat, forgoing what would have been one of the most hotly contested primaries in the 2024 cycle.

The former Indiana governor and Purdue University president said he concluded the Senate run to replace retiring Sen. Mike Braun (R-Ind.) wasn’t the right fit for him at this stage of his career.
