My guess is that it will be you who are too depressed. Romney won the election when he proved that Obama's $150 million campaign to portray him as a monster evaporated in the first debate. All he needed to do was close the sale and he did far, far more than that.
You may notice that ALL of the polls have now turned in Romney's favor. He leads in Florida, NC, New Hampshire, Virginia, Colorado and pretty much all of the so-called "swing states." This with the polling organizations STILL over-sampling Democrats.
October 4th debate caused a permanent step-change in the election. Too bad for you.
