This is where the Republicans are making a huge mistake in not coming out against illegal immigration, which IMHO is having devastating economic consequences in black communities across the country.
The Republicans have an official bug up their RNC keester which is telling them that Latinos with their alleged "family values" are "The Republicans of the Future." Ha!
(A) Millions cannot be legally registered. This does not stop the 'rats, but I am damn sure that if one of them were to illegally register as a Republican, the sky would fall. (B) They are voting heavily for the 'rats, whether legally registered or not.
Otoh, a properly marketed show of force on our borders could perhaps win us enough black votes to upset many a liberal applecart.
