"Honored" by Libertarian Party consideration for President, but staying a Republican

From last Friday Night's show on Fox:

HANNITY: I'm a Reagan Republican. You would be more of a libertarian Republican.

JOHNSON: Well, that would be labels that were — be put on me. I've never labeled myself. But I've considered myself a Republican all along. I've been well treated by the Republicans. I think Republicans are open to ideas and — like I say.

HANNITY: So you're running — if you were to ever consider running for president or other elected office you would run as a Republican not as a libertarian?

JOHNSON: Right. I'm going to stay a Republican. Exactly.

HANNITY: OK. The libertarians tried to recruit you at one point to run for president?

JOHNSON: Well, again, nobody directly contacted me. And I was — you know, I was honored by that but no, it didn't happen. And again, I'm a Republican.

HANNITY: Alright, look —

JOHNSON: I'll stay a Republican.
