The Wisconsin Republican Party platform was changed this year to remove the words "permit" from the right to carry platform.
So anyone running in the Republican Party should be asked if they support the party platform when it comes to right to carry.
I can only speak for my assembly district, (the 84th) but both leading Republican candidates support Alaska, Vermont, Arizona style human right to carry. (i hesitate to use constitution carry because rights precede the constitution and the constitution doesn't enumerate all of our rights, only a few)
As to whether its possible. A year ago I would have said no. Now I think it is.
I don't even think it would be a LOT of work. Just a little work by a lot of people.
If every person on OCDO and every WCI member contacted the candidates in their district and made sure they understood "human right to carry" and that the Republican platform supports human right to carry I think its got a great shot.
