Rig, I find your explanation hard to believe. First off, a lot of Hispanics -- especially those who worked hard and bided their time to go through the legal channels to citizenship -- resent illegals "jumping line," so to speak. Second, a lot of Hispanics are from other countries such as Cuba, Puerto Rico, etc., not Mexicao. It is not the case that Hispanics are a bloc favoring unrestricted immigration or amnesty for illegals.

Second, cracking down on employers is the best way to curb illegal immigration from Mexico without making criminals of the Mexican immigrants and harrassing them.

Third, it is the employers themselves, including big business, who really want to keep the supply of poor immigrants coming into the country, who are willing to work for $3/hr. In fact, the Republicans often speak of wanting to implement a "guest worker" program whereby a lot of immigrants would be allowed in legally, to work for wages that are far below our national minimum wage. If anyone put pressure on Obama to stop cracking down on the employers, it was probably the businesses themselves.
