An Internet poll sponsored by Newsmax.com reveals that Americans overwhelmingly favor Donald Trump as their preferred candidate for the Republican presidential nomination in 2012.

Online participants in the poll, which has drawn more than 550,000 responses, also support Trump by a wide margin in a head-to-head matchup with President Barack Obama.

If the election were held today, Trump would beat Obama in a landslide, 68 to 13 percent. But that lead is just as sizeable when Trump faces off against the best and the brightest in the oft-mentioned field of GOP contenders for 2012.

Trump takes 57 percent of the vote in a field including Mike Huckabee, Sarah Palin, Mitt Romney and Tim Pawlenty. His closest competitor, according to the poll, is former Massachusetts Gov. Romney with 9 percent of the vote.
