The biggest casualty so far is the effort to require background checks on all firearms purchases. Sponsors fell a couple of votes short.
"It's not surprising that there'll be some setbacks," said Rep. Jamie Pedersen. "And that gives an opportunity for people to talk about the issue and regroup and figure out how to do it right next time."
But another gun measure did make it out of the House -- a bill requiring felons in gun crimes to register, much like sex offenders register.
The bill's sponsor, Rep. Mike Hope, says it's modeled on registries in New York City and Baltimore.
"We saw huge reductions in homicides in those cities and now that's moving over to the Senate with huge bipartisan support," Hope said.
But other key bills that aren't making it passed the deadline include:
* A measure requiring girls under 18 to let their parents know before getting an abortion.
* A measure starting the family leave act (which gives temporary income for working parents of newborns or adopted children.)
* A measure notifying parents when a sex offender is enrolled in their children's school.
* A measure giving residents of Mercer Island special options should I-90 get tolling.
Beating Wednesday's deadline was a bill that mandates parents be told as soon as possible if their child is placed in an isolation room at school.
Other measures making it before the deadline: One that toughens the penalties in courtroom assaults, one that toughens the penalties for rendering criminal assistance, and a measure that prevents employers from demanding your Facebook ID and password.
Now these measures head to the opposite house where their fate is unknown.
"We send a strong message, let's no play politics," said Sen. Rodney Tom, the coalition majority leader. "We've gone with the R and D theme, both people are on board and let's do some of these bills that are good for Washington state."
Even though 5 o'clock was the cutoff, in reality bills at the state legislature aren't truly dead until the last moment of the session on April 28.
