(CNN) – Former New York City Mayor Rudy Giuliani said he expects the power players in Washington to wait until the final hours of negotiations to strike a deal on the debt ceiling.
"That's a good strategy for both sides," Giuliani told reporters Thursday at an event hosted by the Seacoast Republican Women in Hampton, N.H. "That's what a good poker player does."
The White House and Congress are battling over a deficit-reduction plan to keep the government from defaulting on its loans by Aug. 2.
While Giuliani encouraged Republicans to be flexible on spending cuts, he said tax increases should be out of the picture, calling the idea "a massive disaster for this economy."
The former mayor is traveling through New Hampshire this week as he contemplates a run for the White House-a decision he said he'll have by the end of summer, though he didn't specify a date.
Giuliani also took the opportunity to blast Obama on the economy, saying the president's policies are to blame for the lagging recovery.
"How much worse can the president be in dealing with our economy? There's been no president, including President Jimmy Carter, who's done worse handling the economy," Giuliani said.
Among other decisions, the former mayor especially faulted the 2009 stimulus package as a major mistake by Obama's administration. When asked if he would have accepted stimulus money as mayor of New York, Giuliani said he would have "absolutely" rejected the funds.
"And if I were in Congress I would have voted against it," Giuliani said. "And if I was the president, I would have never even thought of it."
During a speech at the event, Giuliani said should he run for president, he would change his campaign style from his previous bid in 2008. Last time, the Republican candidate was often criticized for not making enough appearances in New Hampshire.
What Giuliani regrets, though, is the way he handled those appearances, saying he organized them like presidential press conferences with too much hype. He said that instead of being introduced before a speech, he would walk into a room with music and leave with music blaring, as well.
"People were all unnerved, saying 'Why does he think he's so damn important?'" Giuliani said.
If he had a second chance, the former mayor said he would take a more down-to-earth approach and have honest dialogue with voters.
"Let them tell you what they really think," Giuliani said. "And tell them what you really think."
