Automatic voter registration passed the state house in 2013 but failed 15-15 in the then 16D-14R state senate when
a Democratic state senator voted with Republicans against the bill. That state senator is still in office but the state senate is now 18D-12R after the 2014 elections so the bill's chances look pretty good. The new Governor has already announced support for it as she was the one pushing for it as Secretary of State.
Considering that Oregon is about 1.2% of the national population, a rough estimate is that this change (using DMV data to automatically register voters) would add 24 to 40 million new voters to the registration system if it was adopted nationwide.
