Key Points
• Joe Biden’s victory in South Carolina re-established him as the main challenger to Bernie Sanders.
• There is some indication their battle could break on regional lines, with Sanders fighting for inroads in the South and Biden for access to the North. Biden’s task on Tuesday is protecting the six Southern states from incursions by Sanders (and perhaps others, including the unproven Michael Bloomberg).
• Sanders will lead in delegates after Super Tuesday. The question is by how much.
• Texas, both Southern and Western, is the most interesting state to watch on Tuesday. CONT.
