Two Democratic Senators from Central Wisconsin voted against the same sex marriage ban, but it passed the Senate early today anyway.
A proposed amendment to Wisconsin's State Constitution prohibits civil unions.
Senators Russ Decker and Julie Lassa voted it down. However, on a vote of 20 to 13, the amendment passed early Friday.
The controversial same-sex amendment still needs to be approved by both houses in the next session of the Legislature. It would then have to be approved by voters in a referendum.
It could be on the ballot by July of 2005.
