Adopting a softer tone of voice, name-checking people and issues that evoke an emotional response, dropping a few buzzwords that appease one’s critics, even wearing a better-fitting suit…none of this matters.
What matters is details. Plans and timelines. Dates, names and places. Specifics that can be debated, agreed or disagreed with, and voted on.
Absent those, it’s just empty promises and rhetoric.
No matter what the pundits say, don’t confuse acting presidential with being presidential.
