The Washington, D.C. Democratic primary is June 14. The Republican primary is March 12.
What to watch for in Washington, D.C.
The last two primaries are Tuesday, including the Washington, D.C. Democratic primary, where Bernie Sanders and Hillary Clinton will battle for delegates for the last time before the conventions. After Clinton's decisive victory last week in California, the most populous state in the country, media outlets declared Clinton the presumed Democratic presidential nominee. However, last week Sanders said he would continue to compete against Clinton and attempt to push the party further left.
