The poll finds that Clinton leads former Florida Gov. Jeb Bush 49-43 in a two-way race. But if Trump ran as an independent, Clinton remains on top with 44 percent, Bush gets 29 percent and Trump 20 percent.

“The 2016 election cycle has already had its share of ups and downs,” says Dr. Lee M. Miringoff, Director of The Marist College Institute for Public Opinion.  “But, what a rollercoaster ride it would be if Donald Trump runs for president as an independent.”
