That last group - Hispanics - comprises the fastest growing segment of the electorate, and millions made their feelings clear in street demonstrations denouncing the House measure and calling for passage of a broader measure.
translated:
The democrats and republicans care more about potential votes, then the majority of the existing citizens who have expressed that they do not want an amnesty. Thus they caved into empty threats by illegals and radical latino organizations and made a joke of the entire US legal system, border enforcement, and its laws.
Come November, vote everyone of them out. Few exceptions there, Tancredo, Sensenbremmer, Hayworth... FR as a community should compile the definitive list. I've got only D's to deal w/ in Congress, but I'll work to replace them with an alternative D. Vote them out, this is not their job for life.
IMHO, the RINOs aren't trying to capture votes from the illegals for themselves. Rather, they're trying to ensure that the Democrats remain enough power that they can argue the need for "moderate" Republicans. The RINOs are more than happy to allow Democrats to cheat, since it prevents their real enemies (conservatives) from gaining too much power.
