Its called the Frankenstein Veto. It used to be much stronger than it is now due to a 2009 Amendment.
2010 probably caught them all napping.
Dems around that time were entirely naive. They thought Republicans would not abuse a system of consensus and they relied on an outdated sense of the country. Hence dummymanders in Arkansas and hamstringing in Wisconsin.
Weirdly; the Republicans in Wisconsin in the 2010 redistricting actually made all the same mistakes in the way they redistricted as Democrats did in Arkansas, and that Republicans did in Tennessee; yet they lucked out on their gamble where Arkansas Democrats did not and where Tennessee Republicans failed to take.
