We’ve been burned by WI politicans pretty regularly.
Yes we have, but there are some stellar ones, too, just like the rest of the party.
But also keep in mind that even the ones usually considered burners are the ones that turned Wisconsin (and in some ways the rest of the Republican party) from being socialist into slightly-right-of-center. Pribus, for example, deserves a lot of the credit for getting a republican majority in the WI state house, and therefore owning the redistricting, and therefore giving the US house probably two extra Rep congressmen.
They aren't all as far to the right as I would like. But they aren't all Gwen Moore, either.
