Done, except to (800)432-1599, which appears to be out of order (or overloaded).
I justified my non-constituent call by saying, "A Dream Act Amnesty may not seriously impact Maine. But if the Senator votes it in, it cuts our throat in states to the south of you, where we have over 10% illegal aliens and over 20% unemployment among the minority population, who are most often those displaced by illegal aliens."
In other words, I focused on the effect locally on the majority minority population which is most impacted by illegal alien amnesty, relating that to the displacement of local students by a possible Dream Act. That seems to me the most effective approach to liberals.
