Rubio, Kasich and Cruz pledge that they WILL support Trump if he wins - and front-runner grudgingly says he would back one of THEM

  • 'Yes I will,' Donald Trump said when asked on tonight's Detroit debate stage whether he would support the Republican nominee  
  • Trump's other competitors onstage were all asked if they would support the billionaire as the nominee - they all said yes  
  • The question comes seven months after Trump, at another Fox News debate, said he wouldn't commit to supporting the GOP nominee  

Donald Trump came full circle at tonight's Fox News GOP debate in Detroit by promising – seven months later – to support the Republican nominee. 

'Even if it's not me?' he first answered and grinned. 

Before giving his answer, Trump touted the millions and millions of people he said he brought into the Republican party. 'And, by the way, the Democrats are losing people,' Trump said.

'It's the biggest thing that's happening in politics and I'm very proud to be a part of it and I'm going to give them some credit too, even if they don't deserve it,' Trump said, motioning to his three rivals. 'But the answer is yes, I will.'  

On the Fox News debate stage in August – the last time Trump appeared in the same room with moderator Megyn Kelly as he skipped the network's Iowa debate – the billionaire was the sole person who raised his hand when asked if there was any candidate who, at that time, wouldn't commit to supporting the eventual GOP nominee.

By early September, however, he was holding up a signed Republican National Committee pledge, alongside Chairman Reince Priebus, in the lobby of Trump Tower.

'The best way for the Republicans to win is if I win the nomination and go directly against whoever they happen to put up. And for that reason, I have signed the pledge,' Trump declared at the time. 

Since then, he's given himself some wiggle room to get out of it if needed.

In recent weeks, several issues have cropped up where he's suggested that the RNC is not holding up its end of the bargain. 

There was the debate auditoriums that Trump believed to be filled with Jeb Bush supporters and donors a reaction the frontrunner had after he was booed during two debates.

When Ted Cruz ran ads against Trump on the billionaire's former pro-choice record, Trump threatened to sue 'liar' and 'totally unstable' Cruz, but he complained about the RNC too. 

'Additionally, the RNC should intervene and if they don’t they are in default of their pledge to me,' Trump said in the run-up to the South Carolina primary, which he handily won.

Ohio Gov. John Kasich had the most colorful response when asked if he would support Donald Trump as the nominee: 'I think once it's all said and done I'll be the nominee'

Even this morning, when Trump was defending himself against Mitt Romney who was on the verge of making a big attack in the form of a speech today in Utah, the frontrunner suggested that the people he brought into the party, he would also take away. 

'These millions of people who joined, they're all coming with me,' he said on Morning Joe. 

With Trump winning in delegates and with the most momentum coming out of Super Tuesday the other candidates were asked a slightly different version of the question – would they support Trump if he becomes the Republican nominee? 

'I will support the Republican nominee. Yes, I'll support Donald if he's the Republican nominee,' Marco Rubio said, then went on to blast 'socialist' Bernie Sanders and Hillary Clinton, who is 'under FBI investigation.' 

'She lied to the families of the victims of Benghazi,' Rubio shouted about the Democratic frontrunner.

Next up, Cruz answered in the affirmative.  

'Yes, because I gave my word that I would,' he said, before touting his Super Tuesday win in Texas, one of three states that he gobbled up from Trump. 

Kasich had the most animated response. 

'Yeah,' he began. 'But I think once it's all said and done I'll be the nominee.' 

Kasich then motioned to Trump.  

'If he ends up as the nominee – sometimes he makes it a little bit hard – I will support whoever is the Republican nominee for president,' the Ohio governor said.
