It was noted at the time that Nevada in 2008 was especially poised to swing against the incumbent GOP. This was cause Las Vegas was one of the Housing Crisis hotspots, and the Vegas metro decides Nevada elections. There is a argument then that even with the 2008 landslide, Obama was outperforming expected outcome.
And the flip side of that (though I’d probably could apply to the rest of the state, just less so) is the COVID closures of 2020. I’d imagine those helped the GOP in 2020 and 2022. Remains to be seen how NV votes this year, of course.
