Is a Jackson revival under way? I'm referring not to the late King of Pop but to the 19th century populist president whom his opponents called “King Andrew.” According to Michael Barone, in the 2010 elections Republicans have a chance to knock Democrats out of as many as three dozen insecure congressional seats in “Jacksonian districts.”By itself, this would merely reinforce the identification of the Party Formerly Known as Lincoln's with the white South.
