Theft by Unions

I am on record as being unconditionally against campaign contributions by corporations. I am equally opposed to unions making contributions and the validity of that position has been reinforced by the Wisconsin recall election which Governor Walker won handily. It has now come to light that 38% of union members who voted cast ballots to retain the governor. This is in the face of unions misappropriating their members' dues to support the ouster of Walker. Using members' dues to support candidates for whom many members would not vote is tantamount to theft by the union. Unions and corporations should be banned from making campaign contributions.
