There's a reason that "pressing the flesh" is a common campaign thing.
As many candidates for local or legislative offices have learned, shaking someone's hand, kissing someone's baby, or giving someone a hug is the best way to get their vote on election day. It's called "pressing the flesh," and it's standard campaign fare, whether the candidate enjoys doing it or not.
Making physical contact with someone is a great way to get their vote, generally speaking.
That's why candidate show up at state fairs to shake hands, kiss babies, pet dogs, and hug people. They stand there while a line of people files up to make a personal, physical connection with the candidate. Then, they can go home and say, "I like Joe Blow. He has a good handshake." or "Joe Blow loves children. He gets my vote." or "Joe Blow is such a warm, people person. I'm voting for him, and you should, too."
"Pressing the flesh" is such a powerful tool that just about anyone coming near a candidate for office is going to have their flesh pressed if they get close enough. Count on it. If you don't enjoy personal physical contact, stay out of the handshake line and don't work on the candidate's campaign. You're gonna get touched or hugged if you do. That's how it works.
