George M. Dallas
At the 1844 Democratic National Convention in Baltimore, James K. Polk and Silas Wright were nominated. However, Wright did not want to be vice president, and Dallas was picked as his replacement. Dallas was not at the convention. He was woken up at his home by people from the convention who went to Philadelphia to tell him the news. Dallas accepted the nomination. The Democrats won the election with an electoral vote of 170 out of 275.
