Spoilers: If it could be used to somehow malign Obama in any possible way, Republicans jump all over it even if it's a porcupine with poison-tipped spikes.
I mean, obviously they'd constantly bash him as an "illegitimate president" despite having no problems with Bush, yadda yadda. My question is if Republican states/legislators would actually start proposing and passing NPV bills like many Democratic states did after 2000.
You'd probably see GOP legislators pushing for Maine/Nebraska systems rather than NPV.
