The Party that Abe Lincoln built is no longer recognisable.
Founded in 1854 by anti-slavery expansion activists and modernizers, the Republican Party quickly surpassed the Whig Party as the principal opposition to the Democratic Party. It first came to power in 1860 with the election of Abraham Lincoln to the presidency and presided over the American Civil War and Reconstruction. Today, the party supports a conservative platform (from an American political perspective), with further foundations in supply-side fiscal policies and social conservatism.

Would a landslide victory today decimate the republicans like LBJ's victory over Goldwater did then?
