Really, Rosen just needs to park her campaign in Washoe County and that'll seal the deal. I can't imagine her winning Clark by anything less than double digits in this environment.
This is generally the right strategy - Nevadan pols have this weird tendency to ignore anything north of the Moapa Valley-Indian Springs line. But I also think that the lack of a particularly strong or well-positioned/funded candidate in her old CD3, the continuing incumbency of Dina Titus, and maybe even the controversy in CD4 might lead to lower-than-usual turnout in Clark. Of course, this'll probably be beyond washed out by the national Trump effect + the local Heller effect, but it's something to consider.
