Handshaker

A potentially great statesman is not likely to be by natural inclination an enthusiastic, grinning, and indefatigable handshaker, babykisser and small-talkie walkie; yet, no one who is not an enthusiastic, grinning, and indefatigable handshaker, babykisser and small-talkie walkie can become a great statesman, if it is up to the man in the street, the man on the road, the man on the dirt road, and the man in the blind alley — the electorate, in short.

Rough handshaker — He wants to appear tough and outgoing. He may be trying to hide his own feelings of insecurity.
