(Reuters) – Republicans have picked up a net five seats in the U.S. House of Representatives that had previously been held by Democrats with 185 of 435 races not yet called, Edison Research projected on Tuesday.

For House races, Edison Research is tracking the net number of seats that flip from one party to another, as opposed to the net gain or loss of overall seats by either party.

The number of flips does not take into account seven new seats created during congressional redistricting and two races in which an incumbent Democrat and an incumbent Republican are facing each other due to redistricting.

So far, Republicans have won 157 seats in the 435-seat House and Democrats have won 93 seats, Edison projected.

Edison projected that there had been no net gain or loss in Senate seats for either party with 23 of 35 races called.

Republicans would need to pick up one Senate seat to capture control of the chamber.
