'I guess we're down to one now?' Donald Trump dismisses John Kasich despite Ohio governor STILL refusing to throw in the towel after Cruz concedes

• e-mail

Donald Trump used his victory speech to declare himself the GOP's presumptive nominee, mocking John Kasich who remains in the race despite Ted Cruz bowing out.

While Trump praised Cruz as 'a tough, smart competitor' after his win in Indiana on Wednesday, he completely dismissed Kasich as a rival. 

The Texas senator's departure leaves the low-polling Ohio governor as Trump's only challenger, but the billionaire dismissed Kasich saying the party is 'down to one' remaining candidate.

'I want to thank and congratulate the Republican National Committee and [chairman] Reince Priebus, who I just spoke to,' Trump said in his speech after Cruz conceded. 

'He's doing a tremendous job. It's not an easy job when he had 17 egos and now I guess he's down to one. 

'I don't know, is there a second? Is there a second? I don't know. I'm going to have to ask you folks to explain the status of that.' 

It is now a virtual certainty that Trump will go head to head in a general election matchup with the likely Democratic nominee Hillary Clinton.

The top echelon of the Republican establishment said as much minutes after Cruz capitulated, with Republican Party chief Reince Priebus declaring Trump the 'presumptive' nominee.

'Donald Trump will be presumptive @GOP nominee, we all need to unite and focus on defeating @HillaryClinton,' Priebus said, in an extraordinary move to embrace a candidate the party establishment fought tooth and nail to stop.  

Meanwhile, Twitter was flooded with jokes and memes poking fun at John Kasich for staying in the race against Trump.

Some made references to the voracious appetite recently displayed by the Ohio governor on the campaign trail.

One user saying someone ought to 'pull Kasich out of that deli in the Bronx where he lives now to tell him the news'.

Another commented that Kasich would never drop out of the race before a visit at In-N-Out Burger, a popular fast food chain which operates exclusively on the West coast.

A woman posted a photo of Patrick, the voracious starfish in Spongebob Squarepants, inhaling dozens of Krabby Patties with the caption: 'Kasich is too busy eating his way to California in free campaign food to bow out now.'

Buzzfeed reporter Andrew Kaczynski pictured Kasich looking up while eating a sandwich, pointing to himself and saying with his mouth half full: 'Me?'

Yahoo News editor Colin Campbell had a different vision and imagined the governor putting on his headphone to listen to Eminem's 'Lose Yourself'.
