Fellow Republican Mitt Romney warns against making Trump nominee

Former republican presidential candidate Mitt Romney has warned against making Donald Trump an official nominee for president during the November elections.

“Prospects for a safe and prosperous future are greatly diminished if Mr Trump becomes the nominee,” Romney said in a speech in Utah.

Calling Trump a ‘bully’, ‘dishonest’ and a ‘misogynist', Romney added that Trump has neither "the temperament nor the judgement to be president”, according to international media.

Romney, as well as a number of fellow Republicans have expressed alarm at the prospect of Mr Trump securing the nomination for November's election,  while Trump mocked Romney on Twitter as a "failed candidate" who should not advise on electability.

The BBC reports that top figures in the party, several members of the Republican national security community wrote an open letter describing Trump's "vision of American influence and power in the world" as "wildly inconsistent and unmoored in principle".

"He swings from isolationism to military adventurism within the space of one sentence," it added.

Other attackers of Trump’s statements include the 2008 presidential nominee, John McCain.

Romney has been a fierce critic of Trump, and he warned in his speech on Thursday that his policies are a “threat to the Republican party and to the country as a whole”.

"Here's what I know: Donald Trump is a phoney, a fraud… His promises are as worthless as a degree from Trump University," he added.

Romney further warned that Trump’s nomination would pave the way to the presidency for Democratic rival Hillary Clinton.
