Still, the party committee would wither without its largest donors, including industry lobbyists and wealthy individuals, who are feted at semi-annual DSCC retreats on Martha’s Vineyard and in Palm Beach, Florida, which always feature a large group of Democratic senators who are brought to schmooze with donors. Sanders has been one of the more frequent attendees since entering the Senate in 2007, including two last year, once before and once after he declared his run.
The private events attract around 150 to 200 guests, according to a former DSCC staff member, about half of whom are lobbyists and half are large individual donors. To attend, guests had to donate the federal maximum (currently $33,400 a year) to the DSCC, or raise $100,000.
