Connie Mack IV believes he is building momentum after his head to head debate against Bill Nelson, and has launched into an all-out campaign blitz.

Your Florida Decides station went along for four of his stops over the weekend, including three on Sunday.

From Vero Beach, to Okeechobee, Port. St. Lucie and Stuart, Connie Mack IV made various stops around the state in an effort to unseat Senator Bill Nelson.

Rep. Mack brought along former New York City Mayor Rudy Giuliani to help his cause on Sunday.

Mack launched his bus tour following his one and only debate against the Democratic incumbent Bill Nelson, a debate he and his father Connie Mack III believe he won.

"And that bus tour doesn't stop until Election Day. So, we are going to go out there and work hard for every vote we can get. The people of the state of Florida deserve it. Senator Nelson, I think, has been resting on the past," said Mack.

At a campaign stop in Okeechobee, Mack brought supporters on the bus for a tour.

In Port. St. Lucie, he let Rudy Giuliani give his take on the importance of this senate race.

"We need a change and we gotta get Harry Reid out of a leadership position. If you elect his opponent, Harry Reid continues to be the majority leader. With Connie Mack, we'll have a new majority leader, we will have a new way of approaching the Senate, We'll have a budget from the U.S. Senate, we'll end Obamacare, we'll start reducing the deficit," said Giuliani.

Macks father and mother also took part in the multi-county bus tour.

The elder Mack himself won a highly contested Senate race back in 1988, a race that so far has had a similar trajectory to his son’s Senate battle.

“It’s obviously a very close race, my race was one of the closest in the state’s history. The debate was a key part of the election in 1988, I won mine, I think

Connie clearly won his against Senator Nelson. So we are getting down to these last few days. I would not have won the Senate in 1988 if Bush Sr. had not done so well," said Senator Connie Mack III.

Rep. Mack told News 13 the fact that Mitt Romney has improved in the polls in Florida will win the Mack family another Senate seat.

"We'll see on Election Day how parallel they are, he won by 50.4, I'm shooting for 50.5," said Rep. Mack Sunday afternoon.

Recent statewide polls have had Mack trailing behind Senator Bill Nelson by anywhere from 5 to 7 points.

Mack told your Florida Decides station his internal polling shows a dead heat.
