While I do agree, mostly, with your comments in that this thing called the Democratic party and their work on destroying out 2A rights, Gov Polis is a Democrat and the Governor.
So he is "part of their system" not separate from it.
Likewise, I agree, it isn't just one person behind these gun control laws. So it isnt really effective to focus distain or hatred solely towards one.
There are several house/Senators who have made it their "bread and butter" to introduce and push one worthless law after another.
But Gov Polis is the Gov and, in effect, the leader of the Dems in Colorado.
So yes, he does deserve having some of the frustration directed towards him.
