Not including Kennedy and Johnson, when was the last time that a sitting vice-president was elected President of the United States, before George H. W. Bush did it in 1989?

But no sitting Vice President has been elected President since Martin Van Buren in 1836. In the election of 1832, the Jackson-Van Buren ticket won by a landslide. When the election of 1836 came up, Jackson was determined to make Van Buren, his personal choice, president in order to continue his legacy. Martin Van Buren's only competitors in the 1836 election were the Whigs, who were badly split into several regional candidates. William Henry Harrison hoped to receive the support of the Western voters, Daniel Webster had strength in New England, and Hugh Lawson White had support in the South. Van Buren was unanimously nominated by the 1835 Democratic National Convention at Baltimore. He expressed himself plainly on the questions of slavery and the bank at the same time voting, perhaps with a touch of bravado, for a bill offered in 1836 to subject abolition literature in the mails to the laws of the several states. Van Buren's presidential victory represented a broader victory for Jackson and the party. Van Buren entered the White House as a fifty-five year old widower with four sons. http://en.wikipedia.org/wiki/Martin_Van_Buren#Presidency_1837-1841 http://query.nytimes.com/gst/fullpage.html?res=9B0DEFDB153AF930A25756C0A961948260&sec=&spon= May 18 08, 3:23 PM
