They WILL be alienated by equivocations about morality, but they MAY listen if you raise more of a moral challenge to the lies and torture and lack of responsibility/accountability on the right.

They WILL be turned off by more talk of tolerance and equality, the sort of rhetoric that's EASY to make, but their ears MAY perk up if there is more Democratic talk about justice, standing up to bullies, wiser use of power, planning with allies intelligently and with diplomacy instead of recklessness, making sure the legal system is consistent, etc. It's not the same at all when you tell them to tolerate, as when you say 'stand against bullying/harassment'... when you say tolerate they hear 'tolerate rapists and murders and rioters', but when you speak against homophobes who bully and harass people, they can hear that as justice and decency.

They WILL pick up on the sort of resentment and shallow misrepresentation of religion that comes with time, bitterness, and disrespect for religious people and their beliefs, and they WILL pick up on pretense, they've heard enough of it from the Right, they can certainly hear it if the Left tries it.

They WILL wonder why there is no harsh talk against people who riot over cartoons, no harsh talk over brutal Arab regimes, they MAY listen if the cartoon rioters are condemned as violent parallels to Fred Phelps.

They WILL want to know that people they vote for realize that Arabic tyrannical regimes are bad and dangerous, they don't want to elect a fool or naive person who is in denial, and they MAY listen if Saudi Arabia is revealed for the tyrannical regime that it is, friend thought it's royals are to Bush etc., if the dangerousness of the world is acknowledged.
