Here are the key primary election results from Pennsylvania
Five states hold primaries Tuesday: Idaho, Kentucky, North Carolina, Oregon and Pennsylvania.
Pennsylvania's U.S. Senate race could determine control of the chamber in November, and the primaries on both sides have seen unexpected twists in the final days. There are also a number of House contests being set that could decide control of that chamber, plus a high-stakes race for governor.
Polls close at 8 p.m. ET
