Despite what the polls allege, most Americans -- when asked a neutral/realistically phrased question -- oppose ILLEGAL immigration or granting amnesty.
Unfortunately for the Silent Majority, the Democrats hope to draw in new voters amongst the illegals and many corporate-backed Republicans would rather cater to an addiction to cheap, legally unprotected labor.
Neither party cares what effect this is going to have upon this country's future.
I oppose illegal immigration and amnesty. I also oppose the unrealistic notion or rounding up 20mm people and sending them home. If we simply increased security at the borders and stiffened the penalties for employing undocumented workers the problem would correct itself and the protestors wouldn't have a leg to stand on.
