I agree it's a mess. The Dems have advised Walker they would return if he would allow discussion and compromise. Walker has refused and said the bill stands exactly as it is. The union has said they would agree to all his proposals regarding pension/healthcare if he removed taking away their collective bargaining rights. Walker has refused. I have no idea how this will end.
Edit: Wisconsin Law Enforcement Association, who endorsed Walker, today issues an apology and retraction of that endorsement on their website: http://www.wlea.org/
