Primary Races to Watch on Tuesday 5/15

Overall, 28 Congressional Districts have primaries on Tuesday the 15th. Of these, 13 could be competitive in November. DemWritePress offers a primer on which races to track.


Four states (Idaho, Nebraska, Pennsylvania & Oregon) have primaries on Tuesday. Roughly half of the US House districts in play on the 15th are considered “competitive” by either the Cook Political Report, DCCC, Democrats Work for America and Swing Left. We have included information about these races below, including any specific endorsements by these groups.

In a quirk of this particular Tuesday primary, two of these competitive districts involve sitting Democrats. Because Pennsylvania’s mid-year redistricting caused boundary changes, sitting PA Congresspeople are having to shift their constituencies and introduce themselves to new voters. In some cases this helps to solidify odds of victory. In some cases, not.

Of the thirteen featured races on Tuesday, nine are overwhelmingly considered competitive. To help our readers keep track of what is important on Tuesday night, we’ve included information about races of interest below.

Highlighted districts are sorted into two tiers:

  • TIER ONE: These 9 races have been identified by three to four of the organizations above as “competitive”. This demonstrates overwhelming consensus by those paying close attention that these are races to watch closely.
  • TIER TWO: These 4 races have been identified by one to two of the organizations above as being “competitive”, and so are also worthy of attention on primary day and afterward.

Ultimately – the Democratic victors in these primary races will be important: they’ll be part of the crop of candidates that will require the greatest investment of time, money, energy & advocacy to ensure that Congress flips in November. DemWritePress will develop profiles of them for our November Democrats series. This series is intended to help guide Democrats nationwide, as we collectively attempt to keep track of which races are vital to flipping Congress blue.

So, here’s the rundown of Congressional District races to watch on Tuesday night:
