Doesn't make sense to drop out between Saturday SC vote and Super Tuesday.
Only thing I can think of is there using the Biden win and a MSM 'New Frontrunner' onslaught to set up fraudulent poll results, i.e, all switched from Buttigieg and Klobuchar to Biden as an explanation for a Biden 'miracle' resurgence.
Something about SC has them scared. Is, for example, Biden the only candidate who can keep the majority of blacks on the reservation? That would explain VJ surfacing again.
