Now they are on the same side, and Giuliani was Hicks' guest on Saturday before the Rangers game with the Oakland Athletics. Giuliani is running for President and was in town for a fundraiser and rally at Rangers Ballpark in Arlington.
He also took time out to take a little batting practice against Rangers batboy Michael Harlow. He picked up one of Brad Wilkerson's bats.
"Somebody better tell him there are a lot of swings and misses in that bat," Wilkerson said.
Giuliani, 63, did swing and miss a few times but then started hitting the ball solidly, if not for distance.
"I tried to bunt," Giuliani said. "I was telling your manager I'm a big believer in bunting. I believe the American League suffers from the DH because every player should know how to bunt."
This was not Giuliani's first visit to the Ballpark. He was a guest of Hicks back in 2002 and was invited to throw out the first pitch at a game. Since then they have become close friends and Hicks is a major supporter of Giuliani's Presidential bid.
"He's a wonderful guy and a great competitor," Giuliani said. "I should know. I played golf with him today, and he was into every shot. But he's a really good man, one of the most successful businessmen in the country. He's done a great job with this team. He cares about the team, and he cares about his players. He's a player's owner."
Hicks is still good friends with President Bush and twice has brought a group of Rangers players to the White House to meet with him. But now he is putting forth his efforts to head Giuliani's campaign in Texas as a chief fundraiser.
Hicks said Texas has donated more to the Giuliani campaign than any other state except New York.
"I really admire him," Hicks said. "He's such a refreshing politician. He's a leader. You ask him a question and he never gives you a political answer. He tells you what's right. With my concerns on what's going to happen in this world in the next 5-10 years, I want this guy as our leader. I'm going to do everything I can to help him get elected."
This is the third time Giuliani has held a fundraiser in conjunction with a baseball game. He held one earlier in Anaheim and Detroit. Both times the Yankees were the opposing team.
"One time they lost 18-9 and the other I think it was 15-0," Giuliani said. "So I stopped doing them at Yankee games."
