There's a very long list of things within the political system that lack common sense. Is that the converstaion or is the conversation the bogus claim that Democrats are trying to flood the country with illegals in order to gain votes? That's two different converstaions.
I mean it would be common sense to eliminate pork barrel spending. It's commons sense to eliminate lobbying and the $4.5 Billion dollars spent on bribing politicians of all/any party. Stopping the PoTUS pardoing convicted criminals (Dems or Rep) would be common sense. . . . 3 off the top of my head without even thinking about this.
It's a good point to bring up in that it's a problem in our country.... even though it's not the problem that GOP tries to spin it as. Historically, larger-turnout elections tend to favor democrats (with this last presidential election being a significant outlier). So it makes sense that they want to make it so more people that can vote should vote.
That's NOT the same thing as them unofficially adopting the practice of stuffing the voter rolls with people that aren't supposed to even be here.
