She is being primaried by the same Uncle Ruckus as last time (Don Samuels). He's funded by right-wing "think" tanks and ideologues while he slaves like a stevedore in an attempt to hide those connections. It's kind of hard to do so, however, when everyone remembers Samuels' abortive attempts to voucherize the Minneapolis public schools (he also recommended "blowing up" the North High campus). So Omar is probably just flexing her "moderate, reasonable" chops to get some of that sweet DNC money. The PMC/lanyard types are always complaining about Omar being too "radical", so it's probably playing safe on her part to do this (especially because Samuels came close to beating her last time).
