The pressure to act now, be ready now is likely very intense.
Not all politicians are born extroverts, polished public speakers and People-Persons. It’s a lot easier to succeed if you are.
Some poor to average public speakers are still quite competent in their field, but being open, friendly, somewhat bold and media savvy is how most politicians are judged for their first impressions.
A more obvious example of an honorable and highly competent person who was not made for public life would be Dr. Ben Carson. I think he was offered the position of Health Secretary for Trump, but he turned it down.
That makes sense, but how did he manage to campaign successfully before?
Maybe I just missed it all.
