Why is it that conservatives, when discussing any other aspect of a job (pay, working conditions, abuse, etc) will say that "you have a choice; you don't have to take the job," but when it comes to unions, suddenly everyone is forced?
This is absolutely not true in the least. Unions tend to support candidates that will help and support them, just like anyone else who backs any other candidate.
Why are you asking me? Go find some conservatives and ask them.
Perhaps asking someone who has actually made both those statements would be more helpful than asking me.
