Clara, the same reason that you and the Fred supporters tout as why he has waited is the same reason Hunter still has a chance. It’s still three months before the first primaries. Hunter, being a Representative, had to enter a little earlier than many of the others to build a base (although in all fairness it was Hillary IIRC who announced first). He is slowly starting to catch on.
May the best candidate win.
Sounds like the Paulistinians are out in force.
