The 46-year-old, six-foot-three Republican gave Obama a bear hug, raising him off the ground as Obama marveled at the man's strength - and enthusiasm.
Van Duzer owns the Big Apple Pizza and Pasta Italian Restaurant where Obama stopped on Sunday during a Florida bus swing. He also runs a foundation that helps collect blood for the ill; he has received White House commendations for his work.
As he entered, Obama admired Van Duzer's biceps, saying "Look at these guns!"
Said Obama: "The guy's just got a big heart, along with big pecs."
Of his embrace, Van Duzer said: "I was overwhelmed when I saw him."
He said Obama had his vote.
