Asked why Republican Presidential candidate Donald Trump seems to be the only one taking “very aggressive” stances on issues from immigration to radical Islam, Trump campaign manager Corey Lewandowski says, “It’s about leadership,” today in an interview on Breitbart News Daily.

“The difference that you have with Donald Trump and everyone else in the field is, you’ve got one proven leader, an individual who has unbelievable success in the private sector,” he added. “Everybody else in the field talks about it.”

Lewandowski said, “They all talk a great game” but the problem with politicians is, they talk about things, then blame everyone else when they don’t get done. “It doesn’t work that way in the business world,” he concluded.

When host Stephen K. Bannon asked him if Trump plans to back off any of his statements on building a wall, or a temporary ban on Muslim immigrants, for example, “It’s the exact opposite … we’re going to double-down on everything we do,” insisted Lewandowski.

Lewandowski cited Trump’s newly released campaign ad as an example.

In terms of the Clintons, Lewandowski claims the Clintons fear Trump’s ability to counter-punch, not only hard, but based upon his knowing them and their sordid history better than most. He believes a Trump versus Clinton race would win states for the GOP that it hasn’t won for years, potentially similar to what happened during the Reagan landslide of 1984. Polls do show Trump has a great deal of support among blue collar Democrats, just as Reagan enjoyed.

While praising the new ad, Lewandowski said, the ground game is really the most important thing. “We have been very clear from when Mr. Trump launched his campaign. Our efforts are putting people in the states so they can go and talk to the people – not building this massive headquarters in New York, or anywhere else, because the most important thing is getting people to show up and vote on election day.”

He also said the team was built for the long haul and Trump will go to the Convention no matter what his delegate count is at the time. The entire worthwhile interview can be heard below.
