What makes you think he will not? My reasoning is because Romney is going to carry Wisconsin, Michigan, Pennsylvania, Ohio, Virginia, NC, and FL.
That's fine, but if he does carry those states (esp. MI and PA), then I think it is highly probable that Romney finishes with at least 54% of the popular vote, which would be an impressive victory. I hope you are right.
I cannot understand your conclusion that Obama will win an electoral majority but lose the popular vote. What combination of states would do that?
Here are the so-called toss-up/swing states: NC, FL, VA, CO, NH, NV, OH, WI, IA, MI, PA.
I think Romney will win NC, FL and VA by at least 3 points or more (NC he'll probably win by 5+). And I think he will win CO, but it will be close.
On the flip side, I think Obama wins PA, MI and NV.
That leaves OH, WI, IA and NH as the states I'm not that sure about - they are all really close. The Obama victory scenario plays out if he wins OH and WI, which is definitely possible, if not probable. If he wins those two, and even loses IA and NH, he still wins the EC with 271.
And all of this can happen with the current national polls ranging anywhere from Romney up by 1 to 4 points. I think it is likely Romney's popular vote margin falls somewhere in that range.
It will certainly make political history if that scenario plays out. It would be even more significant than Bush/Gore, because Gore only won the popular vote by less than a half percent - i.e., it was essentially a tie. But if we elect a president who loses the popular vote by 2 or 3 points, it will be a very interesting 4 years. As if our country isn't divided enough, this will just add more to the fodder.
