Our ratings for competitive races that feature two members of the same party facing off in November are below (a further explanation of these contests can be found here ). Incumbents are designated with an "(i)":

A note on the color scheme: Blue and red seats are held by Democrats (D) and Republicans (R) respectively. Purple seats feature matchups between a Democratic incumbent and a Republican incumbent (S, for "split"). Green seats are new seats (N) created by decennial reapportionment pursuant to the census and are controlled by neither party.

Republicans currently control 240 of 435 seats in the House, Democrats 190. Five seats are vacant. 218 seats are needed for control of the chamber, meaning Democrats need a net gain of 28 seats to retake the House. All seats not listed on this chart are considered "Safe" for the party which currently controls them.
