If Donald Trump does not secure the Republican presidential nomination, some supporters want him to make a third-party bid for the White House. Alex Pfeiffer of the Daily Caller reports.

A former Pat Buchanan adviser has launched a petition that threatens to launch a new political movement if the Republican Party fails to nominate Donald Trump.

Paul Nagy founded the Draft Buchanan movement in 1992 and went on to serve as his Northeast campaign director. On Sunday, he launched a petition titled “We Will Walk,” which currently has over 1,000 signatures.

The petition states: “Let it be understood that if Jeb Bush, Ted Cruz, John Kasich, Mitt Romney and the Republican Party power brokers steal the Republican nomination from Donald Trump at the convention — when Trump is the clear leader — we will walk out of the Republican party and not support its nominee.”

Nagy told The Daily Caller Monday that he thinks the chances of Trump of having the plurality of delegates and not receiving the nomination is over 50 percent. He said he is working now “to make sure if that happens there is a vehicle for Donald Trump to step into.”

The former Buchanan adviser said a new political movement rising out of the GOP’s exclusion of Donald Trump would not be one exclusive to the New York real estate developer. He told TheDC, “I believe that this movement transcends Trump individually. I mean this is about the country. It’s like Trump said ‘do we wanna have a country or not?’”

Nagy added, “It doesn’t have to be Trump. I mean this movement can take hold and that’s one of the things I hope to be a part of. I want to bring down the current Republican Party. I want to get rid of the impotent snobs.”
