Today's device is to offer opponents "confidence building" measures to assuage their anxieties about amnesty. OK, I'll bite. Here are mine:

 I am open to an amnesty plan after the flow of new illegals has been halted and we have seen significant attrition from the existing illegal population.

I am open to amnesty after - and only after! - federal judges start assisting local law enforcement agencies that wish to enforce the law rather than forbidding them to do so.

I am open to amnesty after a US president demonstrates a willingness to respond with some modicum of respect to the immigration concerns of the American public - and is not looking for any transparent gimmick that will get him from here to the bill signing.
