Officials expected to finish their recount late Tuesday or Wednesday, and Gore had already gained more than 100 votes on Bush at midday. Senior Republicans and Democrats alike said Gore could net another 400 to 600 votes in Broward County alone if the dimpled ballots are allowed.

Circuit Judge Robert Rosenberg, a Republican with Democratic ties, was named to the three-person Broward County elections board to replace Jane Carroll, who abruptly quit Monday.

Still further up the coast, Palm Beach County is the key to Gore's recount drive. The vice president had picked up only a handful of votes with one-fifth of the precincts counted, not nearly enough to overtake Bush, according to senior Democrats. Officials there are not considering any ballots with dimpled chads or with chads detached at one corner.

Party lawyer Dennis Newman, overseeing the Palm Beach recount for Gore, said there were 557 ``dimpled'' ballots for Gore and 260 for Bush that hadn't been counted as officials completed work on 176 of the counties 531 precincts. Those figures were not disputed by senior GOP officials.

Democratic sources say they believe there may be hundreds more dimpled ballots in Palm Beach County once all the votes are reviewed, and Bush's team doesn't disagree. Democrats are asking a local court to force the canvassing board to apply a broader standard for accepting votes.

About 1,500 overseas ballots were rejected for having no postmark or other technicalities. Republicans believe a significant number of them were from military personnel and GOP supporters.

In Dallas, three Texas voters sued to block Bush from being president by challenging running mate Dick Cheney's status as a Wyoming resident. The lawsuit was filed hours after a similar lawsuit was dismissed in Florida.

The suit filed Monday claims Cheney is a resident of Texas, and that he and Bush, therefore, shouldn't be awarded the state's 32 electoral votes. The suit cites the 12th Amendment, which prohibits the president and vice president from inhabiting the same state. Cheney was a resident of Texas until he changed his voting registration to Wyoming just before his selection as Bush's running mate.
