Show boating or not, is it actually wrong to find these people in contempt and issue arrest warrants for them? A minority group of people who are intentionally stalling the democratic process.
Minor difference it's not an "arrest warrant", it's contempt of the State Senate. Like if the fed.gov Senate holds hearings, and you refuse to honor a subpoena etc.
The Master of Arms for the Senate does have Senate rules/WI constitutional authority (in theroy anyway) to drag members into the chamber by the scruff of the neck to force a quorum if the President of the Senate has called them into session.
So it's not "showboating", at least within the borders of WI.
How to negotiate that or extradition with IL is another matter though.
The stakes are kind of high for the WI Senate Dems, as the Senate only has to catch
one of them, and dump them on the floor, and they can then vote, the Senator can wail, scream, refuse to vote etc. it does not matter, they just need his warm body there for the quorum.
If one more Republican had won (one Dem held his district by 400-odd votes) it would not have been an issue, as the Republicans would have been sufficient in number to quorum all on their own.
