In the end, what matters more than anything else is the general economy of the nation. When the US dollar loses its status worldwide due to staggering debt, you will lose your job, pension, healthcare, and home. And your contract with the company won't be worth the paper it is printed on. Asking the teamsters to accept the fact people ought to have a god given right to choose union or not, is of little consequence. All it does is force the union to EARn membership, rather than coerce it. The right to join is constitutional and will never be taken away.
Voting Romney here.
