Do you believe every public official that makes a 'less-than-brilliant' statement summarily should resign?

Specifically I refer to Secretary of Veterans Affairs Robert McDonald’s statement:
“When you go to Disney, do they measure the number of hours you wait in line? Or what’s important? What’s important is, what’s your satisfaction with the experience?”
and subsequent Republican calls for him to resign.

If we can hold the politicians to the “That sounded dumb so I quit” standard, I’m all for McDonald resigning.
The Trump presidency should last less than 50 words.
