FOX 7 Discussion: Primaries in six states

It's another big primary night for Democratic presidential candidates.

Michigan boosted Bernie Sanders's 2016 presidential bid, but four years later, that state could either revive his campaign or relegate him to the role of protest candidate.

Michigan, Washington, Missouri, North Dakota, Idaho and Mississippi are all holding presidential contests Tuesday at a critical point in the Democratic race.

Travis County GOP executive director Brian Ruddle and Tara Pohlmeyer with Progress Texas join Rebecca Thomas to discuss tonight's Democratic primary and what it could mean for Bernie Sanders.
