Post-debate poll: Viewers say Bernie Sanders made best case that he could beat Trump
Bernie Sanders' challengers are looking to slow down his momentum, but polling after last night's South Carolina debate shows he remains in a strong position. Anthony Salvanto, CBS News' director of elections and surveys; CBSN political reporter Caitlin Huey-Burns; Zach Montellaro, a campaign reporter for Politico; and Eugene Scott, a political reporter for the Washington Post, spoke to CBSN's "Red & Blue" about the state of the race heading into the South Carolina primary and Super Tuesday.
