Despite the population centers of Oregon being solid democrat strong holds, they are all in Coastal Oregon. Oregon's interior is less developed and more rugged (and reliably Red otherwise) and tend to have areas where a gun is still needed for survival.
Florida, despite a largely undeveloped interior (Name me the largest city in Florida without a coast line OR a giant mouse as a resident. Without google. I'll wait.), the coastal is largely developed and densly populated and the state has a sizeable population from norther liberal states living in its largest population centers (Florida's southern population has more in common with the Northern states, while its northern population has more in common with Southern states). Florida is a lot more prone to swing politics, so the agendas of those in office tend to change dramatically between election cycles. Finally, Florida is very much aware of it's status as "The Oddball" and while Oregon has its own weirdos, they tend to be found in one part (Portland) whereas no one would doubt that stricter gun use laws for Florida Man is the best way to keep the Florida Man off the endangered species list.
