找出为什么在1850年代美国的辉格党土崩瓦解

辉格党是一个重要的政治力量,在美国从1834年到1854年。其成员最初都是由他们反对美国总统安德鲁·杰克逊——在他们心目中一个暴君,他们就被称为“安德鲁·王。”Their name came from the British Whig party, an opponent of the Tories that was known to criticize the monarchy. When Jackson's presidential victories splintered the National Republican Party and the conspiracy-theorist Anti-Masonic Party went into steep decline, some voters suddenly found themselves with no political party to lean on. The Whigs seized the opportunity: if you hated Jackson, you were in. Unfortunately for the success of the party, it didn't have a great many unifying ideas in its platform besides that one. The campaign of the first Whig president, William Henry Harrison, was ideologically void--he rarely shared his opinion on policy matters, preferring to let his "log cabin," down-home image do the talking. Even so, the Whigs were poised to become the most powerful political party in the U.S. until Harrison died just a month after his inauguration. He was replaced by John Tyler, whose anti-Whig stance and dedication to westward expansion would spell the beginning of the end for the Whigs. When the party realized its Northern and Southern factions were divided over slavery, it was all over. Most Northern Whigs defected to the Republican Party, home to future president Abraham Lincoln, while Southern Whigs flocked to the Democratic Party, whose support for the institution of slavery would soon lead to the Civil War.
