This happened in 1800 when VP Thomas Jefferson ran against President John Adams. In those days the presidential candidate with the second most votes became vice president so Jefferson was the VP because he lost to Adams in 1792.

Since then the Constitution has been amended so that the president and vice-president are from the same party. so it is not likely to happen again.
