Why did NV swing back to a swing state after Obama but not NM?

[David Hume]

NV and NM were relatively close in Bush years, although NM slightly to the left. In 2008 and 2012, Dems won both comfortably. Afterwards NV went back to a swing state, but NM was solid on D with about 10 points. Both states have large Latino population. NM is more rural and poorer, which at face value should benefit R. Yet the result is the opposite. Why?

At state level, in NM R never had trifecta after 1930, while D had trifacta almost half the time, even though R did more better at Federal races before the Clinton years. In NV R and D were about even at state level.
