Eh, that seems like a valid point. But I fail to see how the bill isn't a good thing.
The claim that every co-sponsor of the bill is a RAT is not true. Chris Lauzen is one of the main forces behind this bill, and there are other prominent Republicans in his camp. Unfortunately not many in the GOP leadership want to follow his lead, probably because they're afraid of repercussions from the party bosses.
Yes, many RATs sponsor this bill, but so what? It has to do with structural government procedures, not idealogical policy battles. The RATs support it because their party structure is set up that way, it's the IL GOP that deviated from the norm. Being wary of this because the RATs like it would be like saying recall laws are a bad idea because RATs were the ones that put in the books.
