Montana's at-large U.S. Representative Ryan Zinke was confirmed as Interior Secretary Wednesday. Zinke's departure creates the fifth vacancy in the House. Four Republicans have departed to become part of the Trump Administration, while the Democratic Representative is now Attorney General of California.

All five seats will be filled by special election this year; the calendar is below. At this point, only the race in Georgia appears to have a decent possibility of being competitive. That seat, formerly held by Tom Price, is in a Republican-leaning district in the northern Atlanta suburbs. Price easily won reelection by a 62-38% margin last November. However, Donald Trump won the district by only 1.5%, and Democrats would like to make this an early test of the new president's popularity.
