Supreme Court justices expressed concern Monday about the different standards being used in the Florida recounts. At issue is just what kind of ``chad'' constitutes a vote:

_Hanging door, where one corner is attached.

_Swinging door, with two corners attached.

_Tri-chad, which has three corners attached.

_Pregnant, which bulges but does not punch through.

_Dimpled, where there is only an indentation.

Because there are no statewide standards, local officials must determine which chads count as a vote.

Broward County officials, for example, looked for party-line votes and patterns of dimples down the ballot. If someone voted for one party in congressional, senate or local races, elections officials allowed a dimpled vote for president in that party to count.

But in Palm Beach, dimpled votes did not count if votes for other races on the ballot were clearly punched.

The more lax rules in Broward County allowed Gore to pick up 567 votes in the recount there. A partial Palm Beach recount found at least 176 more votes for Gore, but whether to include them is tied up in court disputes.

Lawyers for Democrat Al Gore want recounts to include ballots with mere indentations. But Bush attorneys argue that the varying standards violate the equal protection clause of the U.S. Constitution.
