Why Obama looks better in the electoral college

[argentarius]

Maybe it is not that different that 2004 when Bush, if he had narrowly lost Ohio, would have lost the EV, but had a >2.5 million PV lead.

I don't think that's the case. Bush won Ohio by nearly the same amount as he won nationwide, over 2%, so if Kerry had won Ohio he probably would've also been receiving enough votes elsewhere to win the PV.
