Just a day before Republican nominee Mitt Romney's formal GOP coronation, a Gallup poll reveals some bad news for the former Massachusetts governor.

Regardless of their political affiliation, the majority of Americans still think President Barack Obama is unbeatable in the November election.

Nearly 60 percent of Americans believe Obama will earn a second term, while only 36 percent believe Romney will be moving into the White House.

According to Gallup, Americans are fairly accurate in predicting elections before they actually head to the voting booth.

In 1996, nearly 70 percent of the country thought Bill Clinton was going to beat Bob Dole. And in 2004, the majority of Americans assumed George W. Bush would win another term. And while voters teetered in four out of five of the polls in 2000, Americans predicted a Bush victory.

Of course, Obama supporters are the most confident the president will win re-election, with 86 percent sure of a second term.

Romney supporters aren't quite as confident, but 65 percent of them still are optimistic Romney can beat the president in November.

The good news for Romney is that his underdog status might mobilize more voters to the poll if they sense the race will be close.

Among independents, however, Obama maintains his edge with nearly 60 percent of them confident he will return to the White House.

Incumbent presidents often have the advantage when it comes to public opinion. Only 10 presidents have lost re-election and voters know that its uncommon.

The other factor voters recognize as significant is the candidate's ability to do his job.

Obama again takes the lead with 38 percent confidence that he would make the best president, compared to 31 percent who believe Romney would make the better leader.

Only 12 percent of the country believe both would be equally good presidents.
