The problem is that there are many types of Latinos.
In parts of the Southwest, there are Latinos, mostly of Mexican origin, who are as American as apple pie and have been in this country for many generations. They tend to at least lean conservative.
Then, you have recent Mexican and Central American immigrants, who are typically accepting of government corruption, and usually vote Dem, if legal, and often if not.
Cuban immigrants are overwhelmingly conservative (in comparison) and generally support the US and it’s laws...
Puerto Ricans, first off are US citizens anyway, and tend to be politically somewhere between the Mexican/Central American and Cuban population. However, most Puerto Ricans I know aren’t big fans of illegals.
Actually the division is between Protestant Hispanics and Catholic Hispanics, the Protestants went for Bush at 56% and McCain 48%, they are definitely in play politically, but the Catholic Hispanics are an uncrackable Democrat bloc.
I grew up in Southern California. Witha small handful of exceptions, the latinos there are overwhelmingly Dim. Cubans tend to be conservative. Puerto Ricans, in my experience, tend to be Dims, as well. Luiz Gutierrez, a congress-critter from Chicago, is Puerto Rican and is a rabid leftist who is front and center of the push for amnesty and opening up the borders for a whole new wave of latinos from south of the border.
