On Tuesday, Democratic Gov. Steve Sisolak signed into law a new congressional map that shifts Democratic voters out of Rep. Dina Titus's heavily blue Las Vegas 1st CD to boost vulnerable suburban Democratic Reps. Susie Lee (NV-03) and Steven Horsford (NV-04). The result: all three districts would have voted for President Biden by between seven and nine points, while GOP Rep. Mark Amodei's northern 2nd CD would remain safely GOP.

It's a calculated risk for Democrats, because all three Las Vegas area seats could now be highly vulnerable if 2022 develops into a red wave. According to the Nevada Independent's Jon Ralston, Titus is fuming her seat was diluted with GOP voters, and even a few Democratic strategists worry it could backfire. But if Democrats are losing Biden +7 or Biden +9 seats next fall, they've likely already lost the majority. And privately, Republicans admit this is the map they would have drawn if they were Democrats.

This map could still face legal risks, because it dilutes the Latino share of the 1st CD from 45 percent to 36 percent.
