Donald Trump told Yahoo News that some of his GOP rivals who are not performing as well simply have the wrong mindset.

Said Trump: “A lot of people don’t like to win. They actually don’t know how to win and they don’t like to win because down deep inside they don’t want to win. It’s a deep, deep secret, but they don’t want to win and they don’t think they should be there. And we have some people that are very good and we have some people that shouldn’t be wasting a lot of time, including their own time.”

Donald Trump told Yahoo News that Sen. Bernie Sanders, who describes himself as a “democratic socialist,” isn’t really a Democrat at all.

Said Trump: “I think he’s a communist. I think he’s actually a communist with a socialistic bent. Anybody that would say that the Paris attacks were caused by global warming, there’s something missing. Even the most ardent global-warming believers aren’t buying that one.”

“I always want to think of myself as an underdog. I never want to think of myself as even leading… I am leading. I’m leading substantially… I’m leading everywhere. I still — I don’t — I don’t even think about it.”

“Donald Trump has gained political strength since the Paris terrorist attacks last Friday, according to most of the polls released in the aftermath,” The Hill reports.

“Trump’s gains show him once again confounding Beltway wisdom, where the widespread view was that such a grave event would lead voters to look toward White House candidates who are purportedly more mature and sophisticated than the erstwhile star of The Apprentice. Instead, it seems that Republican voters have found themselves drawn to Trump’s emphatic rhetoric.

Donald Trump bashed President Obama as “out of touch” and having “no strategy” against the Islamic State in Iraq and Syria (ISIS) in a new radio ad airing in Iowa, New Hampshire and South Carolina, The Hill reports.

“I would’ve enjoyed campaigning against Trump.”

“For an hour and 35 minutes, Republican front-runner Donald Trump vented about everything that’s wrong with this country and this election,” the Washington Post reports.

“Gone was the candidate’s recent bout of composure and control on the campaign trail. As Trump ranted on and on, campaign staffers with microphones who were supposed to take questions from the audience instead took a seat, trying to cheer their boss here and there. The audience laughed at times and clapped for many of Trump’s sharp insults. But an hour and 20 minutes into the speech, people who were standing on risers on the stage behind Trump sat down. The applause came less often and less loud. As Trump skewered Carson in deeply personal language, a sense of discomfort settled on the crowd of roughly 1,500. Several people shook their heads or whispered to their neighbors.”

Rick Klein: “Donald Trump knows better than most, if not all, the value of performance art in the act of running for president. Which is just one of many reasons that Trump’s Thursday night rant, aimed at all of his rivals and particularly Dr. Ben Carson, was memorable and remarkable. Trump has lamented his situation – that people expect him to say something new, and maybe outrageous, every time he goes out there. There’s no teleprompter technology yet known that would dictate the pantomime-stabbing, much less the incredulous facial expressions and the invitation for someone to get on the stage and try stabbing him. The Trump-Carson feud, now fully engaged, could get bloody, maybe even literally – good news for the dozen or so candidates now fighting for only the half of the GOP electorate available to them.”
