Real estate mogul Donald Trump said Tuesday he could run for president as an Independent if he's unable to win the Republican nomination in 2012. Trump, the reality TV star who has been flirting with a run for president, suggested that other Republicans vying for the party's nomination are concerned he might wage a third-party campaign, which Trump said he thought was a viable path to the White House. "The concern is, if I don't win, will I run as an Independent? And the answer is probably yes," Trump said in a video interview with The Wall Street Journal. Trump has received surprisingly encouraging poll numbers in recent weeks, surging to a tie for second place behind former Massachusetts Gov. Mitt Romney (R) in the most recent NBC/Wall Street Journal poll/Michael O'Brien, The Hill. More here.
