The Circus is on the ground in Florida, South Carolina, Maryland and New Hampshire to mark the unofficial kick-off of the Republican Party's presidential nominating contest. The week begins as a leading potential candidate, Florida Governor Ron DeSantis, launches his book tour and ends with CPAC, the annual conservative gathering that’s friendly territory for former President Donald Trump, who’s already in the race. John Heilemann, Jennifer Palmieri, Mark McKinnon and guest host Tim Miller examine the fault lines already emerging in the party.
