Pretty darned meaningless. With the Senate's business done for the year, they'd have to come up with some creative constitutional manuevering just to replace Republican Mike Ellis as Senate President. Right now, nobody sees that happening.
And this talk from the left of the Senate now being a firewall stopping Walker and Republicans, again, they won't be in session again this year, barring the aforementioned sleight of hand they'd have to use to get to the floor.
This piece mentions the Holperin and King seats as being the primary targets of Republicans in the fall in a quest to regain control of the Senate. Agreed, but I believe Dave Hansen's Green Bay area seat is extremely vulnerable. Hansen danced through the rain drops in the recall when State Representative John Nygren failed to get enough nominating signatures. Hansen won't be that lucky this time. I think it's likely Republicans pick off all three, especially if it's a big night for the GOP in Wisconsin.
My definition of that big night? Duffy and Ribble re-elected, the open Senate seat goes to the GOP and Mitt Romney carries Wisconsin. If all of that happens I virtually guarantee those three seats go GOP.
