Donald Trump, the controversial Republican presidential frontrunner, on Saturday asked his supporters at a Florida rally to raise their right hands in a pledge to vote for him, a gesture some found was evocative of the Nazi salute. "Raise your right hand. I do solemnly swear that I — no matter how I feel, no matter what the conditions, if there's hurricanes or whatever — will vote, on or before the 12th for Donald J. Trump for president," the bellicose tycoon yelled at the crowd. As the rally complied, he said "Thank you. Now I know. Don’t forget you all raised your hands. You swore. Bad things happen if you don’t live up to what you just did." This is poised to become the latest scandal in a campaign plagued with them, especially when the firebrand billionaire is involved.
