When Andrew Johnson ran for the Senate in 1855 he heard that his life had been threatened at an upcoming appearance. When he took the podium he pulled out a pistol and laid it on the table in front of him. "Fellow citizens," he said, "I have been informed that part of the business to be transacted on the present occasion is the assassination of the individual who now has the honor of addressing you. I beg respectfully to propose that this be the first business in order. Therefore, if any man has come here tonight for the purpose indicated, I do not say to him, let him speak, but let him shoot." In those days we elected a higher type of man.
