A better way to say it is that Las Vegas is leftist. The rest of the state certainly isn't. But when more than 50% of the population lives in that one city, they control the politics of the whole State. Oregon has the same problem with Portland. New York has the same problem with New York City. Illinois has Chicago. Rinse and repeat.

"We're after power and we mean it. You fellows were pikers, but we know the real trick, and you'd better get wise to it. There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. Well, when there aren't enough criminals, one makes them...you create a nation of lawbreakers – and then you cash in on guilt. Now that's the system, Mr. Rearden." - Floyd Ferris

The reaction will indeed be interesting. In typical chicken-shit petty tyranny style, the edict became effective on this last Friday. Like Friday document dumps, they hope that more headline grabbing crises will supplant this as news.
So it will be left to the matter just spreading by word of mouth - the media, even local, will avoid coverage of any adverse reaction as much as possible.
With a year or more of history on this matter behind us, no doubt much of the individual citizenry will be pissed as all get out and disobey. There will be those, particularly in the 3 bigger cities (where the larger media outlets lurk) that will fall for the variant panic mongering.
The interesting part will be the reaction of the business entities - the stores, restaurants, etc, to this. It will also be predictable that the larger chains - the Wal-marts, Targets, Taco Belches, etc will immediately fold and comply in the hope that the smaller competition will continue to be wiped out.
I am especially interested to see how our County Commission handles this.
