The state’s $6 billion budget and a $600 million tax system overhaul are still in the works, but legislative leaders are holding out hope the session could adjourn as early as Friday.

Also on the legislature’s plate is Gov. Chet Culver’s $750 million bonding plan to pay for flood repairs and work on Iowa’s aging infrastructure. On top of it all, opponents of same-sex marriage have said they will push for legislative action on a constitutional amendment banning same-sex marriage before the session is over.

Four pieces of legislation backed by labor unions are also still on the table, although their future appears bleak.

The session isn’t officially scheduled to end until May 1, when lawmakers’ daily expense payments run out. But Democrats set a goal of ending the session early in order to save money and help with the state’ budget shortfall.

The first hurdle for Democrats will come Tuesday, when debate is scheduled for their controversial tax reform bill that includes ending federal deductibility. A public hearing on the plan last week became so heated House Speaker Pat Murphy asked state troopers to clear the public from the gallery.
