The South Carolina primary polls opened as we went to air this morning. Since 1980 the winner of this Republican primary has gone on to become the party’s presidential nominee. On today’s first hour of “Up w/ Chris Hayes” we discuss the implications of Mitt Romney’s tax records and Newt Gingrich’s recent rise in the polls. Plus, an extended discussion on tax policy and Best Thing You Read This Week.

Joining Chris are Libertarian presidential candidate and former two-term governor from New Mexico Gary Johnson, msnbc contributor and soon-to-be-host Melissa Harris-Perry, Washington Post columnist and msnbc policy analyst Ezra Klein, Pulitzer Prize-winning writer and Reuters columnist David Cay Johnston, and senior writer for Newsweek/The Daily Beast Michelle Goldberg.
