If ever there was a chance that an Independent could win the Presidential Election, now is the time. Jon Huntsman just announced that he would not be attending any Republican events, including the Convention; and any future events until the Republican Party started focusing on the Nations needs, and stop the Politics. Most American's would agree with that position. Also, Huntsman distanced himself early on from the political foray (and even Ron Paul likes him).
It is highly unlikely that Romney could win, and Obama's charismatic appeal seems to be waning. Most Americans are very concerned that the political bickering has gone way to far, and even may have damaged the credibility of the entire process.
Huntsman, after all, was Obama's choice for the critical position of Ambassador to China. Even Obama would have to consider voting for Huntsman, after all Huntsman was his choice.
Probably won't happen, but it sure would be good for the Democratic Process. So, just for fun, write in Jon Huntsman when you vote, miracles can happen.
