MIAMI — As the Florida Legislature sprints into action on Tuesday for its annual two-month session, lawmakers will face the politically volatile task of redrawing the electoral map (sure to attract a court challenge) and devising new ways to plug a $2 billion deficit in the state budget.

But it is the “do we, don’t we” battle over whether to allow resort casinos into the state that has the state capital’s adrenaline pumping. The bill, which proposes opening the door to three large casinos in Florida, is expected to be one of the few major nonbudget-related pieces of legislation to be voted on this busy session.

With a few powerful Republican lawmakers either opposed to the bill or skeptical of its benefits and the session packed with other business, odds that resort casinos will be setting down stakes this year in South Florida, where major casino companies have shown the most interest, are getting longer. Some lawmakers worry that casinos will do more harm than good by tarnishing Florida’s wholesome beach-and-theme-park image, a position espoused by the influential Florida Chamber of Commerce, the Florida Restaurant and Lodging Association and Walt Disney World.

The first test will be on Monday, a day before the session’s official opening, when the bill, which was revamped last week to try to garner more support, is scheduled to face an initial Senate committee vote. The biggest change made to the bill involves giving voters a say on the casino issue, a tactic that could make it more difficult for lawmakers to oppose it. A referendum would let voters decide whether to expand gambling in their county and allow all counties to compete for one of the three casino permits. The casinos would have to invest at least $2 billion to qualify.

“Let the voters decide if they want or don’t want it,” said the Senate bill’s author, State Senator Ellyn Bogdanoff, a Broward County Republican.

State Senator Dennis L. Jones, the Republican chairman of the Senate’s Committee on Regulated Industries, which is to vote on the bill on Monday, said Friday that he would support it. Ms. Bogdanoff, he said, had addressed most of the committee’s concerns in her revised bill. Mr. Jones also pointed out that while the bill would expand casino gambling, it would also pave the way for much-needed large convention centers and hotels in the state.

“We have cut the budget in the last three years, and when they get up there and realize we are another $2 billion short, you get the feeling maybe the time has come,” Mr. Jones said. “We need some new revenue.”

But one of Ms. Bogdanoff’s chief opponents is State Senator John Thrasher, a Republican from north Florida who is the chairman of the Senate Rules Committee, the bill’s final stop before it reaches the Senate floor. He has made it clear that he believes the bill would harm the state and could dissuade families from visiting, a position taken by most conservatives in the Legislature. Republicans hold a supermajority in the Florida House and Senate.

“I do not believe we ought to be expanding gaming,” Mr. Thrasher said. “I think we have enough gaming in the state of Florida. We are not known as a gaming state, in spite of what some folks have said. We are known as a tourist-oriented, family-friendly tourism state. And to change the brand of Florida at this point to a gaming state, to me, is going in the wrong direction.”

Ms. Bogdanoff said she had received assurances from the Senate president, Mike Haridopolos, that if the bill cleared the committees, he would allow an up-or-down vote on the Senate floor.

Some Democratic leaders said they were concerned about allowing private casinos in South Florida. They said they worried that the bill was moving too quickly.

“I think that the bill has serious problems,” said State Senator Nan H. Rich, the Democratic leader, who sits on the committee scheduled to vote Monday.
