Reportedly motivated by a feud with former Florida Governor Jeb Bush over a failed business deal, sources close to real estate tycoon and 2016 Republican presidential candidate Donald Trump claim that Trump has vowed to stop Bush from ascending to the presidency.

In an article by New York Magazine’s Gabriel Sherman which gives an inside look into Trump’s presidential campaign, a friend and informal adviser to Donald Trump quoted the celebrity billionaire as having said, “If I’m going down, then Bush is going down with me. He’s not going to be president of the United States.”

Below the headline in Sherman’s article, which focuses on the nuts-and-bolts of Trump’s 2016 presidential campaign, details are found which point to the emergence of a heated and personal feud between Trump and Jeb Bush. Reportedly, Trump blames Bush for Univision’s cancellation of its contract to televise the Miss USA Pageant.

“While Trump assured me that he thinks Bush is ‘a nice person,’ he has told friends in private that his animosity is personal. According to one friend, Trump blames Bush and Mexican billionaire Carlos Slim for Univision’s decision in June to cancel a $13.5 million contract with Trump to televise his Miss USA pageant. Five days later, Slim scrapped a deal with Trump to develop shows in Mexico. Trump responded by filing a $500 million lawsuit against Univision. ‘Trump believes it all goes back to Jeb,’ the friend says. ‘He thinks Jeb and his wife, Columba, are close with Carlos Slim and Univision got pressure from Slim operatives.’ In a move that further confirmed Trump’s suspicions, Univision has hired Miguel Estrada, a Washington lawyer with deep Bush ties,” wrote Sherman.

Trump plans to best a recent $10 million television ad buy by Bush’s Right to Rise super-PAC by spending “whatever it takes.”

Another friend of Trump reportedly told Sherman, “[Trump’s] numbers are going to come down, and then he’s going to panic. He doesn’t believe it will ever happen. He has not confronted this in his mind.” Sherman theorized that a drop in the polls might motivate Trump to carry out “a kamikaze mission against the candidates left standing.”

Meanwhile, Donald Trump continues to ignore the Republican National Committee’s request that he take a pledge not to run against the GOP’s eventual nominee if he loses the primary.

When asked if he would consider withdrawing from the race, Trump told Sherman, “I only want to go all the way.”
