Explanation:

By the 1860´s presidential election, the Democratic Party had split into proslavery Democrats in the South and antislavery Democrats in the North, so each ran different candidates. The Whigs were unable to take advantage of the situation because they were also divided over slavery and endured a lack of leadership after the deaths of Clay and Webster. The political void seemed helpful to the new Republican Party, which had its first elected president, Abraham Lincoln.

Since then, third parties usually helped to strengthen the two major parties, although a new third party may divide the vote of the leading one.

The Bull Moose party was formed by a former Republican President and Jane Adams. Democrats and Republicans worked together to destroy the Whig party.
