Trump Campaign Mgr: ‘I’m Not Concerned’ About Losing Iowa

[excerpt] 
TAPPER: "A brand new CNN/ORC poll shows Donald Trump has a healthy lead with Iowa's Republican voters, but the story gets a bit more complicated when you single out the voters who actually bothered to show up for the last caucus in 2012. Joining me now, Donald Trump campaign manager Corey Lewandowski. Corey, thanks so much for joining us. As you just saw Mr. Trump's lead in Iowa is substantial over Cruz and the others, but if you only look at voters who have caucused before, it's a neck and neck race. How are you going to get your voters who didn't bother to caucus last time to do so this time?"
LEWANDOWSKI: "Well, hey, thanks for having me on. I think what you'll see here in Iowa and you'll see it across the country is people have been so disenfranchised with politicians who are all talk, no action, that they've stepped away from the process. What we've seen now with Mr. Trump is that he's energized these people, not just in Iowa but across the country. We saw it yesterday in Tulsa, Oklahoma, where 15,000 people came out in the middle of the day to listen to his vision, to make America great again. We see it here in Iowa with these record-setting crowds. These people are so invigorated. They're so excited. They wait in line for hours in the freezing cold to get inside to listen to his message that I'm very confident those people who show up on caucus night for 30 minutes to cast their vote for Mr. Trump I think that's going to happen. I think anybody who doesn't think that is probably missing what's really going on here in Iowa."
TAPPER: "Well, it might happen. I don't know. But as you know better than I do, the caucus process, it's very difficult, it's very involved. It's not just a matter of going and voting. Are you going to have buses to get people out in bad weather? Have you trained your supporters in public speaking?" 
LEWANDOWSKI: "Well, you know, again, it's a misconception. It's really not that difficult to go and caucus. You have to be at a certain location at a specific time, you listen to people make some speeches, and you can write the name Trump on a piece of paper. It's a secret ballot, you write the name down, and you're all done."
