I am this far (holds thumb and index finger about a quarter of an inch apart) from throwing in the towel. I think that the abandonment by the Democrats in the Senate of their constitutional duty to oppose tyranny (unitary executive, just for starters) and not filibustering until real change occurs at the highest levels of the government will be the last straw. Alito's elevation to the highest court will be an offense that cannot be forgiven. The 30-40 years of his ultra conservative rulings will put America on a path to permanent tyranny.
So what is the answer? If we are abandoned by the current Democratic party, then we must in turn abandon them.
