Count U.S. Sen. David Perdue among the politicians impressed with Donald Trump's outsider vibe.

The above video was to be played on Saturday at Trump's first campaign appearance in metro Atlanta but apparently never got used. In the clip, Georgia's junior senator heaps more praise on the billionaire Republican front-runner.

"Donald Trump has struck a nerve in America," he said. "He's inspiring all of us to make America great again."

Perdue has yet to endorse a presidential candidate. But he and Trump spoke by phone last month on the finer points of building a campaign around being an outsider. After the call, Perdue said his jean-jacketed businessman image started it all:

"These candidates are listening (to me). You hear 'em talking about being the outsider now all of a sudden," he told Daniel Malloy. "Where did that come from? We've been screaming about that for two years."
