314 PAC is a political action committee focused on supporting scientists and engineers running for political office. The most active of the three political action committees focused on science, 314 PAC has endorsed only Democratic candidates to date.
In this cycle, 314 PAC has endorsed 5 candidates, four of whom are incumbents (Representatives Bill Foster of Illinois, Louise Slaughter of New York, Seth Moulton of Massachusetts and Jerry McNerney of California). The non-incumbent candidate is Shaughnessy Naughton, a trained chemist running for an open seat in Pennsylvania.
Naughton is also the founder of 314 PAC, and this is her second campaign for the House. Her experience running for this seat in 2014 (she narrowly lost in the Democratic primary) was part of the motivation for her forming 314 PAC. There are a total of five candidates running for the seat, two Democrats and three Republicans. The primary election (likely dwarfed by the ongoing Presidential campaign) is on Tuesday the 26th.
