John Bell was one of the four candidates who ran for President of the United States in the 1860 election. He was a former Whig Party member and had served in Congress and as the Speaker of the House.
In terms of qualifications, John Bell had a significant amount of political experience and was well-known in his home state of Tennessee. However, his candidacy was controversial because he was seen as a compromise candidate between the North and the South, which were becoming increasingly divided over the issue of slavery.
Ultimately, John Bell did not win the 1860 election, with Abraham Lincoln winning the presidency. Whether or not he was qualified to be president is a matter of opinion and can be debated, but his candidacy did play a significant role in the lead up to the Civil War
