Well, the trenchant political analyst, Michael Barone, has now predicted that Romney will win the presidency with 315 electoral votes to Obama's 223: http://www.nationalreview.com/author/200447
And George Will--another serious thinker--has Romney up by 321 to 217: http://therightnewz.com/?p=13384
From these analysts, it would appear that the fat lady has sung.
Before we declare the contest essentially over, however, we should probably note that no less of an authority than Larry Sabato predicts an Obama win, 290 to 248: http://www.centerforpolitics.org/crystalball/
So I guess we will have to wait another 24 hours to find out, for sure...
