Though there are primaries in seven states tonight, including two run-off elections, a lot of the action is in New York's competitive House races.

What to watch: Four incumbent Democratic House members are facing progressive challengers in New York, and Democrats are hoping to flip at least three GOP-held districts. There's one Republican House member with a GOP challenger, but he has President Trump's support.
