the ability to get on with or appeal to ordinary people
An obsolete sense of common (which comes from Latin communis meaning affable) may have influenced this phrase, as may a Shakespearean phrase used in his play about the great exponent of the common touch, King Henry V, on the eve of the battle of Agincourt : a little touch of Harry in the night.
1910 - Rudyard Kipling - If you can talk with crowds and keep your virtue, Or walk with
Kings - nor lose the common touch.
