Primaries are being held today in Pennsylvania, Nebraska, Idaho and Oregon. In Pennsylvania, it will be the first time voters will cast ballots in the redrawn congressional districts. All four states have gubernatorial elections this fall; Pennsylvania and Nebraska also have Senate races. Nominees will be chosen today, although none of these six races are seen as highly competitive in November at this point.

Pennsylvania

As noted above, many voters in the Keystone State will not see their current Representative on the primary ballot as the state's congressional districts have been redrawn. 

Looking at the House ratings from Sabato's Crystal Ball, 6 of the state's districts look competitive or potentially competitive in the fall, while 7 are safe Republican, 5 safe Democrat. FiveThirtyEight has a good overview of some of the more interesting primaries here, as well as races to watch in the other three states.
