This market resolves to "Yes" if Marie Perez (D) wins the congressional election in Washington's 3rd district with a margin of victory that meets or exceeds the margin required by the Cook Political Report. The resolution criteria also consider whether Perez wins by a significant enough margin to surpass the ratings from Inside Elections and Sabato's Crystal Ball. If Perez wins by less than the expected margin, the market resolves to "NO" if the Republican opponent (John Kent) is not considered the likely winner in the event of a tie. The resolution source for this market is a consensus of credible reporting and will be updated as more information becomes available.
