Republican presidential frontrunner Donald Trump is no stranger to controversy, but on Sunday, February 28th, he would not condemn the KKK, after the white supremacist group's former leader endorsed him. This latest controversy -- just two days before Super Tuesday. On March 1st, voters in 11 states will head to the polls.
Donald Trump and Democratic presidential candidate Hillary Clinton are in a position for big Super Tuesday wins.
Even Governor Scott Walker, a long-time critic of Trump, says the path looks good for Trump now.
This, as the other candidates try to forge their way forward.
Trump was tripped up on Sunday over the endorsement of former KKK leader David Duke.
"I know nothing about David Duke. I know nothing about white supremacists. And so you're asking me a question that I'm supposed to be talking about people that I know nothing about," Trump said.
Trump's rivals swooped in.
"Every day it's another thing," John Kasich said.
"He was interviewed on CNN and asked to disavow the Ku Klux Klan and refused to do it," Marco Rubio said.
Trump leads in most of the 13 states where Republicans will vote on Super Tuesday.
Governor Walker said it's fairly likely that his one-time nemesis wins the GOP nomination.

"But that would be conventional wisdom. What we found in this presidential campaign is that conventional wisdom really hasn`t been very conventional, so who knows what`ll happen," Walker said.
Like Trump, Clinton has won three states.
"Tomorrow, this campaign goes national!" Clinton said after her South Carolina primary win on Saturday night, February 27th.
Clinton leads the polls in most of the 11 Super Tuesday states where Democrats will vote.
Marquette University Poll Director Charles Franklin says a problem is forming for anyone not named Clinton or Trump.
"Once you`re behind in the delegate count, it`s very hard to win subsequent states by enough to make up the deficit you have in the delegates," Franklin said.
Republican presidential candidate Ted Cruz is the first candidate to have to defend his home state of Texas.
"I think if we nominate Donald, Hillary probably beats him," Cruz said.
Democratic presidential candidate Bernie Sanders is downplaying his long odds ahead of Super Tuesday.
"Tuesday, over 800 delegates are at stake, and we intend to win many, many of them," Sanders said.
Kasich, one of five Republicans still in the race, played prognosticator on Sunday -- saying he thinks Trump will win every one of the Super Tuesday states.
It is an open question as to whether Wisconsin will play a role in one, both or neither of these races on April 5th.
