Primary Election Dates 2018: A Full State-by-State List

This November's midterm elections are some of the most highly anticipated in years. Polling shows Democratic voters favor impeachment, and Republicans have warned that President Donald Trump could be impeached if Democrats take back Congress.

Polling also shows the two major parties are moving further and further apart, meaning the old strategy for how to win elections (run toward the party base to win primaries, then pivot back to the center to win general elections) is becoming an increasingly difficult balancing act.

While November is still a long way off, primary season began with the Texas primary on March 6, which was set up a showdown between Republican incumbent Ted Cruz and Democratic challenger Beto O'Rourke for one of the state's two Senate seats. On March 20, Illinois held a primary that put in motion what is expected to be the most expensive gubernatorial race in U.S. history, and also ended a bitter battle between a conservative Democrat and a progressive challenger for the state's third House district.
