The Arizona senator joked Wednesday he got the impression Romney is interested in the No. 2 spot on the Republican presidential ticket after watching a recent interview with the former Massachusetts governor.

“I got that impression from him watching his interview last night, I got that impression,” McCain said laughing on his campaign plane in New Hampshire. (Watch McCain’s comments on Romney)

The comments follow Romney’s interview with Fox News Tuesday night, during which the former presidential candidate said he’d be honored to serve alongside McCain.

“I think any Republican leader in this country would be honored to be asked to serve as the vice presidential nominee, myself included,” Romney said. “Of course this is a nation which needs strong leadership. And if the nominee of our party asked you to serve with him, anybody would be honored to receive that call … and to accept it, of course.”

McCain refused to hint at just how seriously his campaign is considering Romney for the ticket, though reports earlier this week said some aides to President Bush are pushing the idea of a McCain-Romney ticket, given the Massachusetts Republican’s credentials with respect to economic issues.

Also says there is nothing but goodwill between the two and that Romney “has a big role to play”.
