Atlas: New Mexico and Virginia are Safe D no matter what!

Yes? Red states are (unfortunately) far more likely to elect a Senator from the other party than blue/Democratic states. There are literally zero blue state Republican Senators right now, whereas you have people like Tester, Manchin, Jones, Brown, and dozens of other very competitive Democrats like Bayh, Bredesen, Kander, et al. in Republican states. PVI is a useless metric when determining the competitiveness of Senate races in red states.
