Well, they do. But the wing of the dems driving this debate is the La Raza wing and the wing that realizes that an underclass of guest workers is just what the dems need.
The dems had huge success with the war on poverty. They created an underclass, fed their resentments, and their kids grew up and vote reliably dem. We're in the third generation now and the dems start their vote counting with 7-10% of the population locked.
It's hard for Teddy Kennedy to pass up institutionalizing another huge underclass--and that's exactly what a guest worker program is. Their kids are citizens but would grow up with the standard underclass resentments because mom and dad are second-class and not worthy of real citizenship.
That an exploitable underclass also benefits the chamber of commerce wing is just an added benefit. The driver is the cornucopia of future resentment-based, government-dependent voters. So the real driver of the democrats' position is the strategic thinkers amongst their leadership.
The Democratic Party label provides good cover for big money’s representatives. Appearing to be furthering the interests of a group like La Raza,(with high profile photo ops) while at the same time secretly pushing the interests of cheap-labor-loving businesses is a perfect setup.
We can see which Senators, Democratic and Republican, that aren’t involved in that deception, by the way they voted.
