Republican presidential frontrunner Donald Trump has warned that his supporters may engage in riots if he fails to secure the party’s nomination for the presidential election in November.

The billionaire businessman has been leading the Republican race by winning one primary after another. Trump won Florida, Illinois and North Carolina on Tuesday which brought him closer to the target of 1237 delegates which he requires in becoming the Republican presidential candidate. The Tuesday primaries also saw Florida Senator Marco Rubio drop out of the race.

Trump also won Missouri in Tuesday’s polls but lost Ohio to John Kasich. The growing popularity of Trump and the increasing possibility of him becoming the next US president prompted his Republican rivals to try to stop him from making it to the end.

“I think you’d have riots,” the CNN quoted Trump as saying on Wednesday. “I think you’d have riots. I’m representing a tremendous many, many millions of people.”

Trump has embroiled himself into controversies time and again, but none has been strong enough to mar his image or hurt his popularity amongst followers. Trump’s rallies comprise supporters of all age groups and creeds. These sometimes even attract people from other countries.

He may have alienated the neighbouring Mexico by proposing to build a wall on the US border with it or have enraged a large section of people by calling for a ban on all Muslims across the world, by not allowing them to enter the US. But all these controversies did little to erode off the massive support behind him.

The indications of a real possibility of Trump winning the Republican nomination is thus, quite clear to most.

Trump made the message very clear for his party on Wednesday saying, “I think bad things would happen, I really do,” Trump said. “I believe that. I wouldn’t lead it but I think bad things would happen.”

According to Republican strategist Ron Bonjean, the party could face real difficulty in blocking him at the convention.

“A contested convention would be justified if Trump only had around 35 or 40 percent of the delegates locked up. However, if he is very close to getting the majority of delegates, it would be politically difficult for the establishment to try to stop him by backroom wheeling and dealing without risking a serious backlash from voters,” the quoted him as saying.
