This is enlightening, particular for those of who read the papers and see the cable news and think all these “Romney has momentum” stories should worry us.

While Mr. Obama can win re-election by carrying Iowa, Ohio and Wisconsin, in addition to holding the other Democratic-leaning states across the country, Mr. Romney must capture more states. Even if he wins Ohio, Mr. Romney still must win Florida, North Carolina, Virginia — and one more state.

I’m trying to remain calm.
