Vermont Sen. Bernie Sanders and former New York Mayor Mike Bloomberg have had the widest and most aggressive footprint across the Super Tuesday states, largely because they've got the money to spend. Bloomberg is advertising in all 14 states, while Sanders is on the airwaves in 12. It's the first time Bloomberg will be on ballots after he skipped the first four voting states, making the day a critical test of his theory that he's the best candidate to stand against Sanders and, later, Republican President Donald Trump.
