Aug. 4 (UPI) -- The Democratic primary for Michigan's Senate seat between Abdul El-Sayed and Rep. Haley Stevens is just one of Tuesday's key races to watch.

Michigan is one of five states holding primaries on Tuesday, along with Virginia, Missouri, Kansas and Washington.

El-Sayed and Stevens are running for the seat left open by retiring Sen. Gary Peters. El-Sayed has received endorsements from Rep. Alexandria Ocasio-Cortez, D-N.Y., and Sen. Bernie Sanders, I-Vt., while Stevens has the endorsement of Michigan Gov. Gretchen Whitmer.

Stevens represents a more moderate wing of the Democratic Party while El-Sayed is the more progressive candidate.
