In 1948, Harry Truman chose to run for a second term as president.
"If I had heeded the desire of my family, I would have made plans to leave the White House at the end of my first term. I took no steps and made no moves at any time to discourage anyone from seeking nomination to succeed me. From a personal standpoint , I had no desire, just as I had none in 1944, to undertake a national political campaign merely for the sake of gratifying private ambitions. I had already been President of the United States for more than three and a half years."
"The compelling motive in my decision to run for the presidency in 1948 was the same as it had been in 1944. There was still 'unfinished business'."
Harry Truman began a 30,000-mile whirlwind tour of the United States to get his message to the people.
