Problem
How does the author, Michael Barone, of the book, How America's political parties change (and how they don't) explain the persistence of the Democratic Party (which dates to 1832 and the election of the Hero of the War of 1812 General Andrew Jackson from Tennessee) and and the Republican Party (which dates back to 1854 with opposition to the Kansas-Nebraska Act which repealed the 1820 Missouri Compromise and instead now allowed for the possibility of slavery in federal territories being organized as states to decide for themselves whether to allow slavery or not)?
