This question gets asked a lot, even in non-legislative session years (the Nevada Legislature meets every two years in odd years, so 2021 is the next session).
Last year, it was the same thing. What are the odds of a constitutional carry bill this year? Campus carry? Parking lot carry? Etc. So a legislator can propose a bill, and in fact in the last two sessions such bills have been proposed. They went nowhere.
In 2017, the Legislature was controlled by Democrats. We had the ability to deny them a supermajority in the Senate. Gov. Sandoval, at the time, wasn't going to sign anything radical like constitutional carry or campus carry. He was termed out and is a RINO.
In 2019, we had a Democrat governor an a supermajority in both houses. As you recall, they rammed through background checks, red flags, and crocodile tears Sandra Jauregui's "kitchen sink" gun control bill. We only avoided a repeal of preemption because the NSSF threatened to pull SHOT Show and the unions ran crying to the Legislature.
With a Democrat governor and Democrat controlled legislature, bought by Michael Bloomberg, we have zero chance of getting a pro-gun bill through. We have every change of seeing whatever abortion they want coming to term, pardon the pun. Nevada's future in 2021 is Virginia today.
The only chance we have to reverse this trend is to elect Republicans and deny the Democrats a majority in at least one house. So you must register to vote, turn out to vote, and vote Republican. If you care about guns, you cannot vote for a Democrat, period. They have been co-opted, except for a single Democrat, Skip Daly.
Unless we somehow turn around this state, which isn't likely due to demographic trends and a vastly better funded and organized Democratic political machine, these bills won't come to fruition. Hell, our corrupt, broken, and feckless Republican party had the chance of a lifetime in 2015 and they blew it.
We life in a time when our ideas are correct and popular, but the tyrants who control us (media, billionaires, and corrupt politicians elected by corrupt political machines) are exerting more power. America in 2020 is more like the early 1770s than you know.
So to finally the answer the question, unless we have a Republican governor and Republican majority Senate and Assembly in 2023, we have no chance of reversing the gun control tide and getting successful bills.
