“I knew that card check is expected to inflate union ranks, but by what means does this mean a guaranteed boost in the Democrat vote?”
In a word, DOLLARS. Millions and millions more of them. From all the union dues collected from newly unionized workers to be lavishly spent on Democrat political organizing and campaigns.
In some sense, an electorate which thinks it can be bought into voting for Democrats deserves the deal. It is a pity that the rest of us have to put up with the consequences.
