No, the margin actually does matter. Every additional vote Romney got cuts in how much of a mandate Obama can claim.
Romney was at least competitive losing by only around 2.5%. Considering how effective Obama's turnout machine was and how awful Mitt's turned out to be, it is pretty clear that the battleground states are pretty close and there is always as much support for Romney's agenda as there was Obama's.
You on the other hand accomplished nothing other than to further prove the irrelevancy of 3rd party's (aside from potentially being a spoiler occasionally). You were a complete nonfactor as I and others correctly told you you'd be. Not one bit of good was accomplished with that vanity run and you should man up, admit as much and use your energies to push the GOP in a better direction going forward. We need intelligent, politically active people like you - and it is extremely sad to see you dedicate your energies to 3rd party timewasters.
As if there was was any appreciable difference.
