Nikki Haley predicted to win Vermont in upset Super Tuesday  victory

Former United Nations Ambassador Nikki Haley was predicted to win Vermont's 17 delegates in an surprising upset victory on Super Tuesday, according to Politico and the Associated Press.

Haley won the Washington, D.C. primary over the weekend but this was her first and only state victory in a Republican race that has been dominated by former President Donald Trump.

The former governor of South Carolina, a state she lost to Trump, did not make public statements during most of Super Tuesday.

While Trump's nomination is looking like a near certainty, political experts say Haley's campaign could spell trouble for him when he faces off against President Joe Biden in November.

Karl Rove warned Republicans that Trump's rhetoric was dividing the GOP and noted Haley drew more than 20 percent of the vote in states such as Virginia, Massachusetts and Maine.

CNN reporter Manu Raju said pro-Haley exit polls in North Carolina should be considered a "warning sign for Trump."
