Senator John McCain is even closer to pay dirt after racking up another win, this time the Wisconsin GOP primary.

The Republican front-runner had an unbeatable lead going into Wisconsin. The win leaves McCain's only rival, former Arkansas Governor Mike Huckabee, even farther behind.

McCain says he's now at the point that even a "superstitious" former Naval aviator can claim he will be his party's nominee.

McCain pledged to run a campaign with "determination, passion and the right ideas" for strengthening the country.

He also praised Huckabee for showing "grit and passion."
