US presidential candidates hit the ground in a last-minute push for votes on Monday ahead of a crucial new election test, with violence marring White House hopeful Donald Trumps race for the Republican nomination.
Dubbed Super Tuesday 2 by US media, the latest major date in the run-up to Novembers presidential election will see Democratic and Republican primary contests in the states of Florida, Ohio, Illinois, Missouri and North Carolina.
The billionaire Trump is looking to build an insurmountable lead, but Republican rivals Texas Senator Ted Cruz, Florida Senator Marco Rubio and Ohio governor John Kasich are more determined than ever to bar his path.
Trump has jetted across the delegate-rich states in recent days, staring down criticism over clashes at a rally on Friday in Chicago — which many saw as a natural consequence of the violent tone of his campaign.
The Republican frontrunners invective has targeted immigrants, Muslims, Hispanics and other minorities, journalists and the disabled — often to raucous approval from thousands of chanting partisans.
But, as with each new controversy swirling around him, Trump seemed unscathed by the uproar with polls suggesting he remained on a glide path toward the party nomination heading into Tuesdays make-or-break round of voting.
Trump, 69, has rejected out of hand any suggestion that his rhetorical excesses have created a climate of violence, blaming supporters of Bernie Sanders for sowing trouble — and threatening to respond in kind by sending supporters to picket the Democratic candidates rallies.
The 74-year-old senator from Vermont, who has pointedly refrained from personal attacks in the campaign, gave a furious retort at a CNN Democratic townhall event on Sunday, stating simply: Donald Trump is a pathological liar.
We have never, our campaign does not believe in and never will encourage anybody to disrupt anything, Sanders added.
It is clear that Donald Trump is running a very cynical campaign pitting groups of Americans against one another. He is trafficking in hate and fear, Democratic candidate Hillary Clinton said.
Trumps Republican rivals, eager to bring him down a notch but also seeming shaken by the weekend violence, have pounced on the frontrunner.
Senator Rubio, who is trailing in third place and like Kasich, faces a do-or-die test in Tuesdays vote in his home state, called Trumps language dangerous.
If we reach a point in this country where we cant have a debate about politics without it getting to levels of violence and anger, he told CNN, were going to lose our republic.
Kasich has accused Trump of creating a toxic atmosphere.
Fridays troubles in Chicago saw ardent Trump supporters and opponents come to blows, after dozens of campaign stops where he has encouraged the crowd to verbally and physically mistreat protesters.
Trump appeared on Sunday to condone one particularly striking act of violence, when a demonstrator was sucker-punched as he was led by police from a rally last week in North Carolina. Trump said his staff would look into paying the belligerent supporters legal bills.
Tensions were palpable at Trumps campaign stops, with Secret Service and police ringing the candidate, after Fridays chaotic scenes and a brief security scare caused the next morning when a protester burst on stage at an event in Ohio.
Trump went on to claim the protester was linked to the Islamic State group — an assertion that he refused to disown, despite it becoming apparent it was based on a crude video hoax.
What do I know about it? he told NBC. All I know is whats on the Internet.
The man in question, a 22-year-old anti-racism activist named Thomas DiMassimo, told CNN he was seeking to wrench the microphone from Trump — and had no desire to cause harm.
I was thinking that Donald Trump is a bully, and he is nothing more than that, DiMassimo said. Hes truly just a coward. And hes opportunistic and hes willing to destroy this country for power for himself.
In Boca Raton, Florida on Sunday, Trump held a generally peacefully rally at an outdoor amphitheater, attended by several thousand people.
Im a better person than the people Im running against, that I can tell you, Trump told his cheering supporters. And Im a better person than Hillary. Hillary is not good.
Earlier in the day in Cincinnati, Ohio, hundreds lined up to see Trump despite the drizzle — while demonstrators massed chanting Build bridges, not walls and No Trump, no KKK, no fascist USA.
A protester holding a Sanders sign interrupted the candidate before being escorted out, to a loud cheer from the crowd.
Its fine, Trump said. In certain ways, it makes it more exciting.
Trump supporter Adam Ward, a 34-year-old Iraq war veteran, said he believed the protesters were actually helping the candidate.
It enrages people that dont agree with Bernie Sanders, he said. I probably wasnt going to come to this until I saw Chicago being shut down.
